This was posted on the old site so I'm hoping Morgan or Tracey or Lance will "pin" it again here.  This is something we can all add to as we find out more toxic/poisonous things.
From the Humane Sociey of US:

	Foods Potentially Poisonous to Pets

And from www.peteducation.com :

Foods to Avoid Veterinary & Aquatic Services Department, Drs. Foster & Smith, Inc.

Q. Which foods could be dangerous for my dog?   A. Some foods which are edible for humans, and even other species of animals, can pose hazards for dogs because of their different metabolism. Some may cause only mild digestive upsets, whereas, others can cause severe illness, and even death. The following common food items should not be fed (intentionally or unintentionally) to dogs. This list is, of course, incomplete because we can not possibly list everything your dog should not eat. Items to avoid Reasons to avoid Alcoholic beverages Can cause intoxication, coma, and death. Baby food Can contain onion powder, which can be toxic to dogs. (Please see onion below.) Can also result in nutritional deficiencies, if fed in large amounts. Bones from fish, poultry, or other meat sources Can cause obstruction or laceration of the digestive system. Cat food Generally too high in protein and fats. Chocolate, coffee, tea, and other caffeine Contain caffeine, theobromine, or theophylline, which can be toxic and affect the heart and nervous systems. Citrus oil extracts Can cause vomiting. Fat trimmings Can cause pancreatitis. Grapes and raisins Contain an unknown toxin, which can damage the kidneys. There have been no problems associated with grape seed extract. Hops Unknown compound causes panting, increased heart rate, elevated temperature, seizures, and death. Human vitamin supplements containing iron Can damage the lining of the digestive system and be toxic to the other organs including the liver and kidneys. Large amounts of liver Can cause Vitamin A toxicity, which affects muscles and bones. Macadamia nuts Contain an unknown toxin, which can affect the digestive and nervous systems and muscle. Marijuana Can depress the nervous system, cause vomiting, and changes in the heart rate. Milk and other dairy products Some adult dogs and cats do not have sufficient amounts of the enzyme lactase, which breaks down the lactose in milk. This can result in diarrhea. Lactose-free milk products are available for pets. Moldy or spoiled food, garbage Can contain multiple toxins causing vomiting and diarrhea and can also affect other organs. Mushrooms Can contain toxins, which may affect multiple systems in the body, cause shock, and result in death. Onions and garlic (raw, cooked, or powder) Contain sulfoxides and disulfides, which can damage red blood cells and cause anemia. Cats are more susceptible than dogs. Garlic is less toxic than onions. Persimmons Seeds can cause intestinal obstruction and enteritis. Pits from peaches and plums Can cause obstruction of the digestive tract. Potato, rhubarb, and tomato leaves; potato and tomato stems Contain oxalates, which can affect the digestive, nervous, and urinary systems. This is more of a problem in livestock. Raw eggs Contain an enzyme called avidin, which decreases the absorption of biotin (a B vitamin). This can lead to skin and hair coat problems. Raw eggs may also contain Salmonella. Raw fish Can result in a thiamine (a B vitamin) deficiency leading to loss of appetite, seizures, and in severe cases, death. More common if raw fish is fed regularly. Salt If eaten in large quantities it may lead to electrolyte imbalances. String Can become trapped in the digestive system; called a "string foreign body." Sugary foods Can lead to obesity, dental problems, and possibly diabetes mellitus. Table scraps (in large amounts) Table scraps are not nutritionally balanced. They should never be more than 10% of the diet. Fat should be trimmed from meat; bones should not be fed. Tobacco Contains nicotine, which affects the digestive and nervous systems. Can result in rapid heart beat, collapse, coma, and death. Yeast dough Can expand and produce gas in the digestive system, causing pain and possible rupture of the stomach or intestines.

Haven't heard that blueberries are bad for dogs, maybe they just didn't agree with her? 

Sorry about your carpet - blueberry on beige can't be good...

Shadowsmom,

At the risk of sounding like a terrible housekeeper, I'll reveal our deep dark secret.  We solve this problem (we have two cats plus Lady) by feeding the cats on a section of the kitchen counter away from where we do our food prep, or on the dining room table.  That way, the cats get to eat what they want, and Lady does not get to graze.  She's too short to counter- or table-surf, unless we foolishly forget to push in one of the chairs, in which case she has discovered how to use it to get up on the table. 

Don't worry, everything gets a thorough cleaning before we or guests eat there!  Cretins that we are , we usually end up eating dinner on the sofa in front of the TV, anyway. 

Ladysmom

Ladysmom,

Glad to hear we are not the only ones that have a "special" area for the kitties on the counter.  We also usually eat in the livingroom

Michelle - Yes, our lives are pretty much completely dictated by the animals.  And we wouldn't have it any other way!

Shadowsmom -- Babysteps!  It's all about babysteps.  I'm sure y'all will reach a mutually acceptable compromise.  Another idea is to feed the cats on top of the washer and dryer. 

Update on Ladybug:  she seems none the worse for wear after last night's urp-fest.   She ate her lunch and dinner without incident, and neither meal has made a comeback appearance.  So, I think the blueberries just didn't agree with her, as Mitzy's Mom suggested.  Crisis averted!

Vicki - I think some of the things on the list are either toxic if eaten in certain amounts which can vary from dog to dog.  Like onions and garlic - garlic is in a lot of dog foods.  With the eggs I can remember my mom putting an egg on our dogs' food when I was growing up - never hurt them. 

Dogs have a different digestive system than humans and can eat raw meat and eggs without usually getting salmonella...but it is possible for them to get it.  Also, if you read the warning about eggs it also because raw eggs contain a certain enzyme that interferes with the absorbsion of something else they need...so it's not just salmonella.

   HELLO ALL I JUST WANT TO SAY THAT I GIVE TAUNEY SCRAMBLED EGGS AND SHE LOVES THEM. I DONT DO IT ALL THE TIME THOUGH. I HEARD THAT IF YOU GIVE A DOG RAW EGG IT IS GOOD FOR THEIR COATS AND THINGS I DONT KNOW HOW MUCH OF THA T IS TRUE OR NOT.

I HAVE ANOTHER DOG HE IS A CHIHUACHUA HE ONLY WEIGHS 4 LBS AND I GIVE HIM PEICES OF CHEESE HE CAN HEAR A CHEESE WRAPPER OPEN A MIL  AWAY, IT HAS NEVER DONE ANYTHING TO HIM, I LET THE DOGS LICK MY PLATES WHEN I AM DONE EATING OR MY BOWLS BUT THAT IS ABOUT AS FAR AS IT GETS.

                                                                                            EVERY ONE HAVE A GREAT FOURTH OF JULY

Oh my goodness.  I did not know about some of these!

I knew about chocolate, and some like string and peach pits are just obvious.  But grapes?!  My goodness.

Christy's story about bones for her dog made me think of my own bone story.  I used to do the same thing with bones from beef ribs- give one to Sam, my lab mix (this was before I had the other 2), and save the rest for the next day.  One time I had like 8 bones or something like that, so Sam had an amply supply of bones over a week's period of time.  At the end of the week I happened to be outside with her in the yard as she pooped.  And my poor dog... hunched over, whimpers and managed to push out these little white rock-like poops!  Poor girl- too many bones constipated her!!!  It was terrible, but yet funny!

That episode put a stop to the bones.... 

thanks for the helpful info

Our chihuahua ate cat food for the last ten years of her life.  We were just careful to not let her eat too much and get too fat.  She started stealing it from the kitty then wouldn't eat anything else.  Monte

Just wanted to add an update to the list - acorns!  Especially, this time of year (fall) when they are falling off the oak trees.  Mine have been eating them for last couple of years...at least Mitzy and Loco did, Mayfly not so much.  But a member has made us aware that they are toxic!!  Acorns contain tannic acid...apparently it depends on how much the dog eats but the toxin can accumulate even if only a couple of acorns are eaten over a period of days!

Really?! Savanna eats them all the time. grrr!
