Some foods that are considered good for people can be very dangerous for pets. The list below highlights some of the most common foods that can be dangerous to animals.

This is not an exhaustive list, and any decision to provide your pet with food not specifically intended for animals should be discussed with your veterinarian or pet nutritionist. For more information on foods that could be unsafe for pets, visit the ASPCA’s“People Foods to Avoid Feeding Your Pets” page.

The following foods may be dangerous to your pet

  • Alcoholic beverages 
  • Apple seeds 
  • Apricot pits 
  • Avocados

  • Coffee (grounds, beans, and chocolate-covered espresso beans)

Special Note: Pennies since 1982 may be fatal if swallowed by a dog because they contain zinc. Also, nuts and bolts contain zinc and don’t easily pass through the digestive system. They sit in the stomach and are dissolved by the stomach acids, slowly poisoning the pet. Symptoms include jaundice, vomiting and difficulty in breathing. If you suspect a dog has ingested pennies or any other foreign objects, have the pet x-rayed.
