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.
Risks to watch for
- High salt in tinned varieties
- Garlic or onion in prepared versions
Potential benefits
- Very low calorie
- High fibre
- Vitamin A, C, K
- Excellent for weight-loss diets
Safe portion size
A small handful as a treat, or up to 10% of their meal swapped for green beans if overweight.
And while you're thinking about what's good for your dog, keeping on top of flea and parasite prevention is just as important as diet.
