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 are not safe either.
This page covers fully cooked, plain kidney beans only. Chili con carne, beans in sauce and seasoned beans are not 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 Can Dogs Eat?
A small amount occasionally. The veterinary guidance we reviewed does not give a specific weight-based amount.
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.
