Serving advice
Treat beans as a snack rather than part of the daily ration — the usual ceiling is about 10% of daily calories. Start with one small piece of beans and watch stools and appetite over the next 24 hours.
Plain, cooked beans (e.g., black, kidney, pinto) are safe for dogs and cats in moderation. Raw or undercooked beans contain lectins which can cause gastrointestinal upset. Canned beans should be rinsed to remove excess sodium. Avoid baked beans with added sugars, onions, or garlic.
Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.
There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter
Garlic and onion damage a pet's red blood cells and can bring on anaemia. Signs are often delayed for several days, so looking fine straight afterwards does not rule it out.
A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.
Added sugar brings empty calories, and over months that means weight gain and dental disease — both far harder to undo than to avoid.
Raw animal protein carries Salmonella and E. coli risk, and those bacteria can spread to the people in the household too.
