The full picture
Green beans are a vet-approved staple for weight management — they're low in calories but satisfyingly crunchy, and replacing some of a dog's regular food with green beans can help overweight dogs feel full while eating less. They can be served raw, steamed, or boiled. Avoid tinned green beans in salted water, and never serve them cooked with butter, oil, garlic, or onion. Plain frozen ones also work.

Safe portion size
A small handful as a treat, or up to 10% of their meal swapped for green beans if overweight.
Does size or breed matter?
No specific toxicity concern from green beans itself at any size — this is mainly a portion and preparation question. Always serve plain and cooked or chopped small where relevant, since whole or large raw pieces are a bigger choking risk for small and toy breeds than for large dogs. Introduce any new vegetable gradually, as too much fibre too quickly can cause loose stools regardless of the dog's size.
