Can Dogs Eat Beans?

Verdict: CAUTION — most plain, cooked beans are safe in moderation; raw kidney beans and seasoned bean dishes are not.

Beans are a good source of protein, fiber, iron, potassium and magnesium for dogs — when cooked plain. But preparation matters a lot: canned and seasoned beans are loaded with sodium, and some beans are toxic raw.

Which beans are safe?

• Green beans (break up the strings)
• Black beans
• Lima beans
• Pinto beans
• Chickpeas / garbanzo beans (cooked thoroughly)
• Lentils

Which beans to avoid

• Raw kidney beans — toxic. They contain phytohemagglutinin, a lectin that can make dogs sick. Cooked, small amounts are OK.
• Refried beans — very high in fat and usually contain garlic, chili powder and salt.
• Baked beans — loaded with sugar, salt and often onion or garlic.
• Canned beans — high sodium; rinse well if you use them.

Symptoms of lectin poisoning (raw kidney beans)

• Vomiting and diarrhea
• Abdominal pain
• Dehydration

If your dog eats raw kidney beans, call your vet.

How much is OK?

Start with a few cooked, plain beans as a treat or food topper. Beans can cause gas and bloating in large amounts. Treats should stay under 10% of daily calories.
