Use care with these items so you don’t drop or track them into areas where your pet may have access to them. What may be a small amount to a human could be a poisonous amount to a small cat, dog, or other animal.

Foods & Drinks Toxic to Pets

Store and dispose of these items securely, out of the reach of your dog, cat, or other pet, preferably in a high cupboard with a child-proof lock. One ounce is all it may take for lasting damage or death, depending on the size of the pet and toxicity of the substance ingested. Below is a list of some of the more common 

  • Caffeine & Chocolates – anything containing methylxanthines, which is found in chocolate and caffeine products such as coffee, tea, and soft drinks.
    • Chocolates & chocolate bars – the darker the chocolate, the more toxic it is. Dogs love chocolate but it hates them!
  • Xylitol – this artificial sweetener can be found in over the counter “sugarless” baked goods, candy, gum, toothpaste, and other products. 
  • Alcohol/ethanol, hops/beer
  • Marijuana
  • Grapes & raisins – even when baked into something else – are highly toxic and can cause rapid kidney failure.
  • Onions, garlic, leeks & chives – these foods all contain allium, and are toxic raw or cooked, fresh or dried; cats are particularly sensitive. 
  • Raw & fish, poultry/eggs, bones, and seafood. Traces of raw meat may cling to all bones, and turkey, duck & chicken bones can splinter and cause a blockage. After removing meat, fish or chicken from bones, double-bag unused scraps and bones and dispose of them in a pet-proof garbage bin.
  • Salt & salty products – ingesting chips and other high-salt snack foods and products (road salt, etc.) can be lethal for pets.
  • Nuts – macadamia nuts, almonds, pecans, and walnuts
  • Rising yeast bread dough
  • Some spices / spice plants – marjoram, mint, parsley, sorrel, saffron, oregano, thyme, tarragon, nutmeg
  • Starfruit, Rhubarb leaves, citrus fruits and by-products (ie, tomatoes, grapefruit, oranges, etc.). 
  • Avocado is particularly toxic for birds.

Advise family members and visitors that food and drinks should never be left unattended on pet-accessible surfaces, and any dropped food items should be picked up immediately – feeding random table scraps to pets could be hazardous to their health. 


  • Food wrappings including candy and chocolate wrappers, should be promptly disposed of in a secure garbage can.
  • Although it’s less common (less than 10% of all dogs and cats), some pets also have food allergies to beef, dairy, wheat, fish, etc.
  • Before buying dried animal products such as rawhide bones, jerky treats, pigs ears, etc. check for recalls here: U.S. Food & Drug Administration Recalls & Withdrawals
