Recording_0680.jpg

The Mars Society is pleased to announce that it has joined the online Marspedia project started by two other space advocacy groups – The Mars Foundation and The Moon Society – in an effort to build out a great resource for people of all ages to learn more about the planet Mars, promote the human and robotic exploration of the Red Planet and encourage STEM education.

The organization is striving to make Marspedia the one-stop shopfor all information related to Mars, including: articles describing past historical missions to the planet, current knowledge about Mars, technology related to ongoing exploration, future concepts such as terraforming and plans for human exploration and settlement of the Red Planet.

The Mars Society is taking a leading role in this effort and has formed a Governing Council comprised of representatives of the three organizations, led by Susan Holden Martin, a Steering Committee member and former Executive Director of the Mars Society, along with James Burk, current IT Director for the organization.

In an attempt to expand the Marspedia project, we are currently looking for interested and dedicated volunteers who are able to help us to improve and maintain the online Mars encyclopedia, which takes the form of a “wiki” that anybody can add to or edit once they set up a free user account.  We are also in the process of improving the overall design of the encyclopedia, including creating a new, modern logo for the project.

For the improvement of the encyclopedia’s content, an Editorial Subcommittee has been formed and is meeting weekly via teleconference.  We need folks to join this subcommittee that have experience with editing and reviewing content, particularly with a science background. In addition, we are always looking for new content that we can add to Marspedia, and can attribute that content with multiple options of content licensing including Creative Commons and public domain.

For technical maintenance and upgrades, a Technical Subcommittee has also been formed and is using the Slack tool for communication.  We already have an experienced group of technical experts that has set up and is maintaining the encyclopedia, but we are also on the lookout for experienced software developers and people that are familiar with the platform we are using: Mediawiki. The Mars Society is working to make Marspedia a cutting-edge and technologically advanced resource that has many tools available for our content writers and editors.

To join this important effort, please visit the main Marspedia web page at www.marspedia.org and access the information under “How You Can Help”, including links to the two subcommittees mentioned above.  If you have content to share, there is a Submission Form available as well, so you can submit your content and have others post it into the encyclopedia.

USA High School Students Want to Work With International Students on A New Mars Lander Project

Get Involved in Mars Society “Red Eagle” Student Contest to Design Mars Lander

Students and from the Barboza Space Center will support other teams that want to try for this new international competition.  Write your letter for possible collaboration and send it to Barboza Space Center (Suprschool@aol.com.  Attention Bob Barboza.

42BA660C-C538-4CD6-8D90AE61E7D29042.jpg

What do I need to do to get started?

The Mars Society recently announced plans for an international student engineering contest to design a lander capable of delivering a ten metric ton payload safely to the surface of Mars. The competition is open to student teams from around the world. Participants are free to choose any technology to accomplish the proposed mission and need to submit design reports of no more than 50 pages by March 31, 2018.

These contest reports will be evaluated by a panel of judges and will serve as the basis for a down-select to ten finalists who will be invited to present their work in person at the next International Mars Society Convention in September 2018. The first place winning team will receive a trophy and a $10,000 cash prize. Second through fifth place winners will receive trophies and prizes of $5,000, 3,000, $2000, and $1,000 respectively. In honor of the first craft used to deliver astronauts to another world, the contest is being named “Red Eagle.”

Background:

The key missing capability required to send human expeditions to Mars is the ability to land large payloads on the Red Planet. The largest capacity demonstrated landing system is that used by Curiosity, which delivered 1 ton. That is not enough to support human expeditions, whose minimal requirement is a ten ton landing capacity. NASA has identified this as a key obstacle to human missions to Mars, but has no program to develop any such lander. SpaceX had a program, called Red Dragon, which might have created a comparable capability, but it was cancelled when NASA showed no interest in using such a system to soft land crews returning to Earth from the ISS or other near-term missions.

In the absence of such a capability, NASA has been reduced to proposing irrelevant projects, such as building a space station in lunar orbit (not needed for either lunar or Mars expeditions), or claim that it is working on the technology for large visionary interplanetary spaceships which will someday sail from lunar orbit to Mars orbit and back, accomplishing nothing.

International High School Students Working Together To Build A Great Experiment for the International Space Station

Who wants to launch a satellite?  Student at the Barboza Space Center are designing, building and repairing satellite prototypes in the hopes of one day carrying their experiments to the International Space Station.  Nanoracks is a company that makes that all possible.

 

NanoRacks Launches Full External Cygnus Deployer, New Customers, and More to Space Station on OA-8

With the launch of the OA-8 mission, NanoRacks has now brought over 600 payloads to space, and introduced numerous new customers to the commercial ISS marketplace.

Wallops Island, VA, November 12, 2017 – Early this morning, the Orbital ATK CRS-8 (OA-8) launch carried another historic NanoRacks mission to the International Space Station (ISS). With a completely full NanoRacks External Cygnus Deployer (ENRCSD), a virtual reality camera, and educational research, this mission marks over 600 NanoRacks payloads delivered to the ISS since 2009.

This mission is enabling a unique virtual reality opportunity with National Geographic’s VUZE camera. Integrated and launched via NanoRacks, VUZE will allow for the recording of the new National Geographic series “One Strange Rock,” in which the astronaut crew will record a series of virtual reality pieces for incorporation into a larger documentary about natural history and the solar system. This is National Geographic’s first time launching with NanoRacks.

NanoRacks is also pleased to have launched the “Microbes in Space” educational experiment. Microbes in Space is one of two experiments launching to the ISS via a partnership with NanoRacks, DreamUp, and Xtronaut as a part of a Kickstarter campaign to build on-the-ground kits that will compare science at home and in the classroom to real science in space. The Kickstarter is now live, with kits beginning at just a $25 donation.

Additionally, OA-8 is the fourth mission in which NanoRacks is providing opportunities for CubeSat deployment from Cygnus after the vehicle departs from the station. The NanoRacks ENRCSD is installed on the exterior of the Cygnus service module with the capability to deploy satellites after Cygnus’ completion of its primary ISS resupply mission.

On this ENRCSD mission, NanoRacks has 14 satellites ready to be deployed with customers including the NRO Office of Space Launch, Asgardia, Spire, Tyvak, NASA’s Jet Propulsion Lab (JPL), and the Naval Research Laboratory in Washington, D.C. Included in this External Cygnus manifest are also The Aerospace Corporation’s AeroCube B/C satellites, water-based propulsion CubeSats.

“OA-8 is yet another unique mission for NanoRacks,” says Senior Mission Manager Henry Martin. “We’re thrilled to have a full External Cygnus Deployer, displaying its maximum capability. This mission also brings new customers from outside the industry into space while continuing partnerships with existing customers like Spire for their ongoing satellite constellation. Notably, this mission will also deploy our first-ever propulsive satellite from the Cygnus spacecraft.”

The ENRCSD satellites are scheduled to be deployed from the Cygnus vehicle early December at an altitude above the ISS orbit, pending all nominal spacecraft operations.

The External Cygnus Deployer includes in the following satellites:
  • ISARA
  • PROPCUBE
  • Lemur-2 (8 CubeSats)
  • Aerocube B/C (2 CubeSats)
  • Asgardia-1
  • CHEFSat
ISARA and Aerocube B/C are funded through NASA’s Small Spacecraft Technology Program (SSTP), which is chartered to develop and mature technologies to enhance and expand the capabilities of small spacecraft with a particular focus on communications, propulsion, pointing, power, and autonomous operations.

Also on board the OA-8 mission are two CubeSats that will be deployed via the NanoRacks CubeSat Deployer onboard the ISS. The satellites, EcAMSat and TechEdSat-6 each come from NASA Ames Research Center.

EcAMSat is a biological CubeSat that will investigate the effects of microgravity on the antibiotic resistance of E. coli, a bacterial pathogen responsible for urinary tract infections.  The EcAMSat flight opportunity is offered by NASA’s CubeSat Launch Initiative (CSLI) as part of the thirteenth installment of the Educational Launch of Nanosatellites (ELaNa) mission, and sponsored by the NASA Launch Services Program (LSP).

By the time the OA-8 External Cygnus mission is complete, NanoRacks will have deployed over 200 satellites into low-Earth orbit.

NanoRacks would like to thank Orbital ATK and the NASA International Space Station Program for their continued support of NanoRacks operations on the ISS.

The self-destructing game of 1986

How one man brought the first high-stakes games to life.

In the fall of 1963, 13-year-old Tom Snyder arrived home from school to find his front lawn covered with crates from IBM. Snyder could hardly believe his eyes, and he was dying to know what the prestigious company had delivered to his door.


Snyder had spent the preceding months building a computer in his basement, cobbling it together with remnants of electromagnetic switches and electronic wiring he’d found thrown out behind several telephone company offices. Their switch to touch-tone phones was his gain, as the outdated relays provided him with enough circuits and components to build a small, functioning, digital machine. Astounded by their son’s technological prowess, Snyder’s parents coerced him to write what he felt was an insignificant letter to IBM’s then president, detailing his electronic exploits.

Once Snyder cracked open the mysterious crates, he found thousands of dollars worth of outdated computer hardware, along with a short note expressing IBM’s encouragement. “Remember us when you’re older,” the last line read.

With his mind racing, the young Massachusetts native set to work putting together a much more advanced computer, complete with a screen and keyboard. While Snyder delved deeper and deeper into the world of electronics, he fell in love with the concept of creating unique digital entities — things that let him add realism and risk to otherwise fantastical worlds.

Snyder’s love for computers followed him into his adult life and he set about creating his own software development company: Tom Snyder Productions. The company started as a pioneer in the world of educational computer tools and games for classrooms and later on developed cult animated shows like “Dr. Katz, Professional Therapist,” “Science Court” and “Home Movies.” If you played around on a classroom computer in the ’80s or laughed at a crudely animated Squigglevision cartoon in the ’90s, chances are you interacted with some of the magic created by Tom Snyder Productions. Though not every project he touched turned to gold, Snyder often attempted to blaze a trail into uncharted territory.

Sub MissionSub Mission: A Matter of Life and Death

FIGHT OR FLIGHT

While working on educational games in the early ’80s, Snyder decided his company would try its hand at designing and programming mainstream video games for the Atari 5200, Commodore 64, PC and Apple II. Snyder ran his company like a party, hiring former students from his stint as a teacher in the ’70s, as well as skilled waitstaff from around his hometown, encouraging his co-workers to find ideas that were different and alluring.

Sitting in his home office in 2016, Snyder recalls the struggles of trying to fit these epic ideas into small spaces: “You had to go in and trick the processor into doing things even it didn’t know it could do,” he says. “The level of ingenuity was different. Making games now is nothing like the breathtaking terror of doing it on a little computer with a finite amount of space.”

Snyder was well known for balancing useful and popular ideas with unconventional attempts. Completing his more profitable programs, like edutainment classics Snooper Troops and Agent USA, Snyder then turned to the radical new ideas he was dedicated to cultivating. The first of Snyder’s games to grab the attention of the media and the gaming world as a whole was a title called The Other Side.

“MAKING GAMES NOW IS NOTHING LIKE THE BREATHTAKING TERROR OF DOING IT ON A LITTLE COMPUTER WITH A FINITE AMOUNT OF SPACE.”

One of the earliest modem-based games commercially available, The Other Sidewas all about working as a unit to literally build bridges and find natural resources with other countries around the world. The game was such a wild idea in 1984 that NBC asked Snyder to come demonstrate the title on an episode of “The Today Show” with other teams of computer programmers from around the globe showing off The Other Side‘s cooperative functions. Snyder knew he was onto something. People liked the variety, the thrill of something fresh and realistic.

“It was around this time that I was always trying to come up with a different angle that made the stakes of the game higher,” he says. “I was looking for a way to make games more real. Less obsessive and more meaningful.”

Snyder wanted players to put more thought into their in-game actions and not waste their digital lives or precious real-world time. These ideals came from personal experience. Snyder found a game that he himself couldn’t put down: Microsoft Flight Simulator. The legendary simulation software was his addiction for hours on end after work, and one weekend while reading up on the game, he decided to raise the stakes, to add a bit of tangible risk to the world of virtual flying.

The following Monday, Snyder shared his new idea with his wife and employees. He was going to war. He would use his flight simulator skills to cross the German borders and take on World War II adversaries within the game, but should he be shot down three times, he would cut his physical copy of Flight Simulator to shreds. Manually destroying a computer program was a mildly expensive investment for a personal experiment that was destined to end in failure, but Snyder was dedicated to bringing something meaningful and exciting to his gaming experience.

“I WANTED TO FEEL LIKE A TRUE PILOT … MY PENALTY WAS ONLY THROWING OUT $40 OF SOFTWARE.”

Crossing over into enemy lines wasn’t something mandatory for players to do in Flight Simulator. In fact, Snyder had no idea how skilled the computer-operated German planes would be. He had only ever focused on the flying part of the game and had strayed away from the combat aspects almost entirely. After weeks of preparation, Snyder suited up in an old leather jacket, grabbed a thermos of coffee and alerted his wife that he would “be at war” in the office if anyone needed him.

Within eight minutes, Snyder lost his first plane.

Staying away from the German borders, Snyder decided to practice some of his maneuvers in the safety of allied skies before heading back in. On his second attempt, he lasted over an hour, managing to shoot down various enemy pilots before he took too much damage and crashed into the pixelized German countryside. Feeling more confident in his abilities, Snyder immediately flew back into the war zone but was once again shot down in mere minutes.

“I was dead,” Snyder recalls in a matter-of-fact tone. “I wanted to feel like a true pilot in the Battle of Britain. Nineteen-year-old kids would go up and it was exciting, but if you ‘lost’ during a war you were dead. My penalty was only throwing out $40 of software.” Though saddened by his short-lived war efforts, Snyder felt obligated to follow through with his promise. He made short work of the Flight Simulator disc with a pair of nearby scissors and left his office to inform his wife of his untimely demise.

THE NUCLEAR OPTION

The exhilaration and reality of Snyder’s bizarre Flight Simulator stunt was enough to plant a seed in his mind. He began to synthesize some of his previous ideas about making a title that would heavily challenge players. Snyder set about dedicating a portion of his professional day to work on his new pet project. His employees, while entertained by his previous game-destroying endeavor, were horrified that he wanted to move forward with the idea as a formal title. “While I was designing it, everyone was trying to talk me out of it,” he says. “Everyone. They said, ‘You can’t possibly sell a game like this.'”

Being the founder of a gaming company had its perks, though. Snyder says greenlighting the project wasn’t so much about convincing others it was worthwhile as it was about asserting that it was happening whether they liked it or not.

“WHILE I WAS DESIGNING IT, EVERYONE WAS TRYING TO TALK ME OUT OF IT. EVERYONE.”

Influenced by the classic Tom Clancy novel, “The Hunt for Red October,” as well as the Cold War warning video “The Day After,” Snyder modeled the game around nuclear sub battles. Though the game would include realistic and meaningful consequences, Snyder still wanted to create a captivating world that players would want to experience. For this reason, Snyder decided to set his game in the distant future on an uncolonized planet known for its sprawling oceans where an evil alien warlord had kidnapped two earthlings and was holding them against their will. The only hope for these two hostages, dubbed Sigourney and Peter, was to beat the antagonist at his submarine wargames. Snyder felt playing up the romance between the captives would give them more human appeal, causing the player to feel responsible for their well-being.

The hook was that if you failed to save the star-crossed captives, your game would more or less self-destruct, refusing to boot for any future gameplay. To give players a fighting chance, Snyder came up with a system that allowed them to practice their sub skills with a robot in place of the human hostages. This way, players could get a feel for the game and even fail a few times before diving head first into the briny depths. It limited the gameplay, however, giving players the same basic scenarios for victory.

“There were a lot of warnings in the game when things were going wrong,” Snyder says. “Every aspect of the gameplay was built to give players plenty of time to pull back and strategize a new plan of attack.” By choosing a robot over Sigourney and Peter, players didn’t have to worry about their fate, but they’d trapped themselves in what was, more or less, a tutorial.

“THERE WERE A LOT OF WARNINGS IN THE GAME WHEN THINGS WERE GOING WRONG.”

Once players finally decided to pick one of the humans, the game changed and the stakes became higher. Every time a human-manned sub managed to best the warlord, the on-board hostage would be able to share information about how all protagonists (including the player) could escape the deadly planet and ultimately beat the game. However, if the player chose a human and lost, that human would stay dead indefinitely. If players lost both Sigourney and Peter, the game would void its copyright protection and become nothing more than a $40 drink coaster.

Despite the naysayers, Snyder worked diligently to complete the game, even going so far as to package it with a cassette full of plot narration and instructions. He wanted people to feel immersed in this small world he had created, if only for a while.

Without much trouble, Tom Snyder Productions pitched and sold the game to the highest bidder. The publisher, Mindscape, only bought the game under the condition that it could add a few more safety nets to the title’s staunch approach to in-game death. Mindscape bundled emergency instructions with the game that let players resurrect each of the human captives once before the disc was rendered unplayable. If these extra lives didn’t help, players could fill out a petition to the Space Commissioner in the game’s instruction booklet and send it in (along with seven dollars) for a replacement disc and a second shot.

DEATH AND REVIVAL

Launched as Sigourney Loves Peter in early 1986 for the PC and Apple II, Snyder’s game was an immediate flop. It wasn’t the hardcore, high-stakes angle that made it fall short, though. According to Snyder, it was the explicit romance. Turns out, no one in the mid-’80s wanted to play a computer game with a focus on saving two captives in love.

Instead of giving up on the idea, Snyder formulated a plan to change the game’s name and focus more on the “white-knuckle drama” that came with the possibility of losing your disc. The rebranded Sub Mission: A Matter of Life and Deathlaunched the following year and while no one would consider it a mainstream hit, it managed to find a small thrill-seeking audience. The bizarre hailstorm of both praise and criticism Sub Mission received was enough for Snyder to know that he had struck an important chord with the gaming community.

Sub MissionSub Mission: A Matter of Life and Death

Snyder, now 66 years old, has long departed from the gaming industry. Asked to look back at his achievements in the world of game design, he still revels in the delight of bringing such a radical game to the table. Despite its peculiar approach, Snyder’s “high-stakes” title has faded into obscurity over the last 30 years, a forgotten relic waiting to be rediscovered. There have been plenty of games — like Steel Battalion, Upsilon Circuit and One Life — that have pushed the limits of what players could lose, but none seem as foolhardy and meaningful as Sub Mission.

Congratulations to Dr. Williams Board Member Honored Nationally

The prestigious Green-Garner Award goes to Dr. Williams our Long Beach Unified School District’s Board Member Was Honored Nationally

Dr. Williams.png

Long Beach Unified School District Board of Education member Felton Williams received the 2017 Urban Educator of the Year award last night at the Council of the Great City Schools’ 61st Annual Fall Conference in Cleveland.

Eleven school board members from big-city school districts competed for the nation’s highest honor in urban education leadership, recognizing in alternating years an outstanding superintendent and school board member from 69 of the largest urban public-school systems in the country.

“I am positively on cloud nine,” Williams said.  “I’m deeply touched and grateful to the Council for this tremendous honor.  While I appreciate the personal recognition, this award also is a reflection of the high quality of our school system in Long Beach and all the hard work of our talented team of educators and support staff, fellow school board members and superintendent, devoted parents, amazing students and exemplary community partners.  I look forward to bringing this award home and sharing it with all of them.”

Urban school leaders applauded Williams during the Council’s annual “Urban Educator of the Year” award banquet, where he received the prestigious Green-Garner Award.

Sponsored by the Washington, D.C.-based Council, Aramark K-12 Education and Scholastic, Inc., the top prize is presented each year in memory of Richard R. Green, the first African American chancellor of the New York City school system, and businessman Edward Garner, who served on the Denver school board.

Williams has been on the Long Beach Board of Education for more than 13 years, serving multiple terms as president and vice president of the 74,000-student school system’s policymaking body.  He has led efforts to improve student academic performance, including the planning and implementation of the district’s Academic and Career Success Initiative.  He developed a program to increase the number of students of color pursuing Advanced Placement (AP) courses and exams, and recommended adoption of an ethnic studies program in partnership with California State University, Long Beach.

The former dean at Long Beach City College earned a master’s degree in business administration at CSULB and a Ph.D. in higher education at Claremont Graduate University, where his professors included renowned business management guru Peter Drucker.

Williams has helped to improve urban education nationally.  He has advocated for the nationally emulated Long Beach College Promise since its inception nearly 10 years ago, when LBUSD, LBCC and CSULB leaders committed to providing all local students specific support needed to prepare for and succeed in college.  He is also the immediate past chair of the Council of the Great City Schools’ Board of Directors.

“Felton Williams has made substantial contributions to urban public education at both the local and national levels,” Council Executive Director Michael Casserly said.  “His passion for equity and excellence has had a profound effect on how all of us serve our urban students.  There could be no one more deserving.”

As the recipient of the 2017 Green-Garner Award, Williams receives a $10,000 college scholarship to present to a student.

“Congratulations, Dr. Williams, on winning the 2017 Green-Garner Award,” LBUSD Superintendent Christopher J. Steinhauser said.  “We can’t thank you enough for everything that you’ve done for our young people.  From the day you stepped on as a board member you’ve been a huge advocate for equity and access for all of our kids, and because of your efforts to lead our initiatives, our district is recognized as one of the best in the nation.”

Comments:

Dr. Williams has helped the Super School Design Center and Barboza Space Center over the past few years with establishing  our summer fellowship programs at the California Academy of Mathematics and Science High School on the campus of California State University Dominguez Hills.  This is a Long Beach Unified School District high school on  a college campus.

People Foods to Avoid Feeding Your Pets

ASPCA Animal Poison Control Center Phone Number: (888) 426-4435

Our Animal Poison Control Center experts have put together a handy list of the top toxic people foods to avoid feeding your pet. As always, if you suspect your pet has eaten any of the following foods, please note the amount ingested and contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435.

Alcohol
Alcoholic beverages and food products containing alcohol can cause vomiting, diarrhea, decreased coordination, central nervous system depression, difficulty breathing, tremors, abnormal blood acidity, coma and even death. Under no circumstances should your pet be given any alcohol. If you suspect that your pet has ingested alcohol, contact your veterinarian or the ASPCA Animal Poison Control Center immediately.

Avocado
Avocado is primarily a problem for birds, rabbits, donkeys, horses, and ruminants including sheep and goats. The biggest concern is for cardiovascular damage and death in birds.  Horses, donkeys and ruminants frequently get swollen, edematous head and neck.

Chocolate, Coffee and Caffeine
These products all contain substances called methylxanthines, which are found in cacao seeds, the fruit of the plant used to make coffee, and in the nuts of an extract used in some sodas. When ingested by pets, methylxanthines can cause vomiting and diarrhea, panting, excessive thirst and urination, hyperactivity, abnormal heart rhythm, tremors, seizures and even death. Note that darker chocolate is more dangerous than milk chocolate. White chocolate has the lowest level of methylxanthines, while baking chocolate contains the highest.

Citrus
The stems, leaves, peels, fruit and seeds of citrus plants contain varying amounts of citric acid, essential oils that can cause irritation and possibly even central nervous system depression if ingested in significant amounts. Small doses, such as eating the fruit, are not likely to present problems beyond minor stomach upset.

Coconut and Coconut Oil
When ingested in small amounts, coconut and coconut-based products are not likely to cause serious harm to your pet. The flesh and milk of fresh coconuts do contain oils that may cause stomach upset, loose stools or diarrhea. Because of this, we encourage you to use caution when offering your pets these foods. Coconut water is high in potassium and should not be given to your pet.

Grapes and Raisins
Although the toxic substance within grapes and raisins is unknown, these fruits can cause kidney failure. Until more information is known about the toxic substance, it is best to avoid feeding grapes and raisins to dogs.

Macadamia Nuts
Macadamia nuts can cause weakness, depression, vomiting, tremors and hyperthermia in dogs. Signs usually appear within 12 hours of ingestion and can last approximately 12 to 48 hours.

Milk and Dairy
Because pets do not possess significant amounts of lactase (the enzyme that breaks down lactose in milk), milk and other dairy-based products cause them diarrhea or other digestive upset.

Nuts
Nuts, including almonds, pecans, and walnuts, contain high amounts of oils and fats. The fats can cause vomiting and diarrhea, and potentially pancreatitis in pets.

Onions, Garlic, Chives
These vegetables and herbs can cause gastrointestinal irritation and could lead to red blood cell damage. Although cats are more susceptible, dogs are also at risk if a large enough amount is consumed. Toxicity is normally diagnosed through history, clinical signs and microscopic confirmation of Heinz bodies.

Raw/Undercooked Meat, Eggs and Bones
Raw meat and raw eggs can contain bacteria such as Salmonella and E. coli that can be harmful to pets and humans. Raw eggs contain an enzyme called avidin that decreases the absorption of biotin (a B vitamin), which can lead to skin and coat problems. Feeding your pet raw bones may seem like a natural and healthy option that might occur if your pet lived in the wild. However, this can be very dangerous for a domestic pet, who might choke on bones, or sustain a grave injury should the bone splinter and become lodged in or puncture your pet’s digestive tract.

Salt and Salty Snack Foods
Large amounts of salt can produce excessive thirst and urination, or even sodium ion poisoning in pets. Signs that your pet may have eaten too many salty foods include vomiting, diarrhea, depression, tremors, elevated body temperature, seizures and even death. As such, we encourage you to avoid feeding salt-heavy snacks like potato chips, pretzels, and salted popcorn to your pets.

Xylitol
Xylitol is used as a sweetener in many products, including gum, candy, baked goods and toothpaste. It can cause insulin release in most species, which can lead to liver failure. The increase in insulin leads to hypoglycemia (lowered sugar levels). Initial signs of toxicosis include vomiting, lethargy and loss of coordination. Signs can progress to seizures. Elevated liver enzymes and liver failure can be seen within a few days.

Yeast Dough
Yeast dough can rise and cause gas to accumulate in your pet’s digestive system. This can be painful and can cause the stomach to bloat, and potentially twist, becoming a life threatening emergency. The yeast produce ethanol as a by-product and a dog ingesting raw bread dough can become drunk (See alcohol).
