Can Dogs Eat Kidney Beans?

LIMIT

SOMETIMES — Fully cooked, plain kidney beans are fine in small amounts; raw or undercooked kidney beans are toxic.

Cooking is what makes kidney beans suitable. Raw beans contain a toxic lectin. Offer only fully cooked plain beans, without salt, sauces or spices.

The full answer

PetMD says cooked kidney beans can be given to dogs in small amounts.

Raw kidney beans are toxic. They contain a lectin called phytohemagglutinin, which thorough cooking destroys. Undercooked beans aren't safe either.

This page covers fully cooked, plain kidney beans only. Chili con carne, beans in sauce and seasoned beans aren't covered.

Risks and Things to Know

  • Raw or undercooked kidney beans are toxic.
  • Canned beans in salty liquid or sauce, and seasoned beans, add salt, onion, garlic or spices.
  • Too many beans can cause gas and stomach upset.

How much is okay?

A small amount of well-cooked kidney beans now and then. Never give them raw or undercooked, which is harmful, and skip tinned ones in sauce.

How Should I Prepare It?

  • Fully cooked until soft, with no salt, onion, garlic or spices.
  • If using canned beans, choose plain beans with no added salt or sauce.

What If My Dog Ate Too Much?

If your dog ate raw or undercooked kidney beans, contact a veterinarian, or an emergency veterinary clinic out of hours, straight away, even if your dog seems fine.

This guide is for general educational purposes and isn't a substitute for advice from your veterinarian. If your dog has eaten something potentially toxic or is showing concerning symptoms, contact a veterinarian promptly.
