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.

No toxicity, so no threshold. Plain fresh or frozen rather than canned, which is usually salted.

How much green beans can a dog have?
Treats and extras should stay under about 10% of a dog's daily calories, so the complete food still supplies the nutrients. At about 31 kcal per 100 g, this is how much green beans fills that allowance on its own for a typical neutered adult at a healthy weight:
| Dog weight | Daily treat allowance | Most green beans per day |
|---|---|---|
| 10 lb | 35 kcal | 113 g (4.0 oz) |
| 25 lb | 69 kcal | 223 g (7.9 oz) |
| 50 lb | 116 kcal | 374 g (13.2 oz) |
| 75 lb | 158 kcal | 510 g (18.0 oz) |
| 100 lb | 196 kcal | 632 g (22.3 oz) |
If your dog gets other treats the same day, those share the allowance. Puppies and very active dogs need more calories overall; dogs on a diet need fewer.
How to serve it
- Fresh or frozen, steamed or raw, with nothing added.
- Canned beans usually contain added salt. Choose no-salt-added if you use them.
- Chop for small dogs.
