Safe. Yes. Green beans have no known toxicity and at roughly 31 kcal per 100 g they are one of the better options for a dog on a diet.
How much is dangerous?
No toxicity, so no threshold. Plain fresh or frozen rather than canned, which is usually salted.
Why it does harm
There is no toxic principle. Green beans is on this list because owners ask about it, and the honest answer is that the risk is about calories, preparation or choking rather than poisoning.
What to look for
- None expected.
What to do
- Serve plain: no butter, no salt, no seasoning containing onion or garlic.
- If you are using them to bulk out meals during weight loss, do it as part of a plan rather than by eye.
