Beans to Avoid

Some beans are unsafe or even toxic to dogs:

• Baked beans – Often contain sugar, salt, and spices harmful to dogs
• Refried beans – Usually cooked with onion and garlic
• Canned beans – High in sodium and preservatives unless labeled no-salt-added
• Raw kidney beans – Contain phytohemagglutinin, which is toxic unless thoroughly cooked
• Coffee beans and cocoa beans – Extremely toxic to dogs
• Fava beans (broad beans) – Can cause vomiting, diarrhea, and other issues

How to Safely Prepare Beans for Dogs

1. Rinse thoroughly – If using canned beans, remove any added salt or preservatives
2. Cook thoroughly – Boil or steam until soft
3. Serve plain – No butter, oil, salt, onions, or garlic
4. Moderation is key – Beans should be a treat or supplement, not a main food source

How Much is Too Much?

Start slow. Beans are high in fiber, which can cause gas or upset stomach if introduced too quickly. For small dogs, a tablespoon or less is enough. Larger dogs can enjoy a few tablespoons occasionally.

Use beans as:

• A training treat
• A food topper
• A snack replacement for fatty or processed treats

Watch for Side Effects

Keep an eye on your dog for signs of:

• Gas or bloating
• Diarrhea
• Vomiting
• Allergic reactions (rare)

If any of these occur, stop feeding beans and consult your vet.
