When Your Pet Ingests a Toxin
Many foods harmless to humans are toxic to pets. Additionally, only small amounts of some household substances can prove harmful to cats and dogs. Call us if you ever suspect your pet has consumed something they shouldn’t have. We can let you know whether you need to worry about what your pet ingested. Sometimes we may need you to contact the ASPCA Animal Poison Control Hotline to assist.
Some of the more common toxins that are the most dangerous to pets include the following:
- Chocolate is toxic to both cats and dogs.
- Xylitol, an artificial sweetener commonly found in gum, is toxic to cats and dogs.
- Onions, garlic and chives are especially toxic to cats but pose a threat to dogs as well.
- Caffeine contains the same ingredient that makes chocolate toxic.
- Grapes, raisins and prunes are specifically toxic to dogs.
- Macadamia nuts can be toxic to dogs as well.
- Rodent/Mouse poison of any kind.
- Antifreeze is highly toxic to dogs and cats.
- Lilies are very dangerous for cats.
What to Do if Your Pet is Injured

- If available, use a muzzle to protect yourself from getting bitten.
