Dangerous substances
Some foods commonly enjoyed by humans are dangerous to dogs, including chocolate (Theobromine poisoning), onions, grapes and raisins, some types of gum, certain sweeteners[14] and Macadamia nuts. It is currently believed that the only dangerous substance in chocolate is cocoa, meaning that forms of chocolate without this compound, such as white chocolate may become re-evaluated for their safety in future.

The acute danger from grapes and raisins has been uncovered only since about 2000, and made public slowly since then. At present the cause is not known, but one veterinarian [15] believes it may be an acute auto-immune response to plant-borne viruses [16] in the same manner as FIP in cats. Whatever the reason, since only small quantities are necessary to induce acute renal failure, dogs should not be fed grapes or raisins, and sultanas and currants should likely be withheld as well.

Cooked bones should never be given to dogs, as the heat changes the chemical and physical properties so that they cannot be chewed properly, splintering into jagged shards, and resist digestion.

Human medications should not be given to a dog as a substitute for their regular medication as some can be especially toxic, especially paracetamol/acetaminophen (Tylenol). Alcoholic beverages pose much of the same hazards to dogs as they do to humans.

Dogs may also find some poisons attractive, including antifreeze, snail bait, insect bait, and rodent poisons. Antifreeze may be one of the most insidious of poisons to dogs because of its sweet taste and because a dog may walk upon or lie down upon a spill of it or its residue and then lick it off. Dogs must be kept strictly away from antifreeze and not allowed access to any place that has had a spill of it that has not been completely removed.

Plants such as caladium, dieffenbachia and philodendron will cause throat irritations that will burn the throat going down as well as coming up. Hops are particularly dangerous and even small quantities can lead to malignant hyperthermia. [17]

Amaryllis, daffodil, english ivy, iris, and tulip (especially the bulbs) cause gastric irritation and sometimes central nervous system excitement followed by coma, and, in severe cases, even death.

Ingesting foxglove, lily of the valley, larkspur and oleander can be life threatening because the cardiovascular system is affected. Equally life threatening is the yew which affects the nervous system. If any of these plants are ingested, get the dog to a veterinarian immediately.

Many household cleaners such as ammonia, bleach, disinfectants, drain cleaner, soaps, detergents, and other cleaners, mothballs and matches are dangerous to dogs, as are cosmetics such as deodorants, hair coloring, nail polish and remover, home permanent lotion, and suntan lotion.

Zinc toxicity, mostly in the form of the ingestion of US pennies minted after 1982, is commonly fatal in dogs where it causes a severe hemolytic anemia. [18]

Dogs will occasionally eat their own feces or the feces of other species if available, such as that of cats and horses. This is known as coprophagia, and may be indicative of boredom or hunger, although there is no definitive reason known. Owners of both cats and dogs may find that dogs treat the catbox as a snack bar. Such behavior should be discouraged, as it could lead to Toxoplasmosis.

Answer 2

Onions are toxic to dogs. The toxicity is dose dependent, so the bigger the animal, the more onion need be consumed to cause a toxicity. Onion toxicity causes a Heinz body anemia. Heinz bodies are small bubble-like projections which protrude from a red blood cell and can be seen when the cells are stained. This "bubble" is a weak spot in the red blood cell and, therefore, the cell has a decreased life-span and ruptures prematurely. The toxic effect of the onions are the same whether the product is raw, cooked or dehydrated. The hemolytic episode usually occurs several days after onion ingestion (lowest hematocrit around day 5 post ingestion). Daily feeding of onions could have a cumulative effect due to ongoing formation of Heinz bodies versus a single exposure with a wide gap until the next exposure, allowing the bone marrow time to regenerate the prematurely destroyed red cells. I would assume that since your dog didnt actually eat the onion that he'd be okay? Yet again, it depends on how big/small your dog is and how big the onion piece was. I really wouldnt be too concerned tho since he didnt consume it and maybe only a little bit of the onion enzymes are in his blood. I would call your vet tho just to make sure. Its always better to be safe than sorry with a loved doggy :)

Answer 3

onions are on the toxic food list for dogs.

The toxicity is dose dependent, so the bigger the animal, the more onion need be consumed to cause a toxicity. Onion toxicity causes a Heinz body anemia. Heinz bodies are small bubble-like projections which protrude from a red blood cell and can be seen when the cells are stained. This "bubble" is a weak spot in the red blood cell and, therefore, the cell has a decreased life-span and ruptures prematurely.
If numerous red cells are affected and rupture, anemia can result. It is a form of hemolytic anemia. Onions are only one of the substances which can cause Heinz body anemia. Other substances such as Acetominophen (Tylenol) and benzocaine-containing topical preparations can also cause Heinz body anemia in the dog.

The toxic effect of the onions are the same whether the product is raw, cooked or dehydrated. The hemolytic episode usually occurs several days after onion ingestion (lowest hematocrit around day 5 post ingestion). Daily feeding of onions could have a cumulative effect due to ongoing formation of Heinz bodies versus a single exposure with a wide gap until the next exposure, allowing the bone marrow time to regenerate the prematurely destroyed red cells.

Answer 4

If your dog ingests enough of a wuantity of onion it wil cause something called Heinz Body Anemia. And yes the dog can die from this.
What happens is the onions interfear with how the red bloods cells work and how long htey live for. It causes them to die off to fast and since they carry oxygen to the bodies tissues the pet gets anemia and they can die.
For some dogs it does not take much onion for them to die from it others it takes much more and it can build up slowly. Like if you feed some each day it could kil the dog in a month.
So yes onions are considered toxic to dogs and they should ne be fed .

Answer 5

Yes, onions can be poisonous. It's best to avoid table scraps at all, but if you do give table food, don't give anything with onions in it. Grapes and raisins also fall into this category, along with chocolate and many other human foods. Their bodies cannot process the same foods that ours can, and they can get very, very sick.

We did have a friend who said his dog ate whole, raw onions and never got sick, but I wouldn't try it. It's not worth an emergency vet visit or possibly losing your pet.

Answer 6

I've heard that onions, grapes, and chocolate are all really bad for dogs (either they can kill them or make them extremely sick). I would definitely not feed my dog onions. Actually, your dog should probably not be eating any people food, just in case. Dog food is specially made for a dog's system, and should not be replaced by (or supplemented with) people food.

Answer 7

They are toxic to dogs. If your dog ate enough, it may kill him.

"Onions and garlic are other dangerous food ingredients that cause sickness in dogs, cats and also livestock. Onions and garlic contain the toxic ingredient thiosulphate. Onions are more of a danger."

Answer 8

Onions are toxic. While it won't likely kill your dog right away, it builds up in their system and eventually can cause organ failure.

The ASPCA has info on their website:

Check it out. Other toxic foods for dogs include chocolate, coffee, grapes and raisins.

Answer 9

Onions can be toxic to dogs and especially cats. They can damage red blood cells

Answer 10

It may not kill the dog, however, onions are toxic to dogs. The dog would not feel well if given these.
