How much bananas 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 89 kcal per 100 g, this is how much bananas fills that allowance on its own for a typical neutered adult at a healthy weight:
| Dog weight | Daily treat allowance | Most bananas per day |
|---|---|---|
| 10 lb | 35 kcal | 39 g (1.4 oz) |
| 25 lb | 69 kcal | 78 g (2.8 oz) |
| 50 lb | 116 kcal | 130 g (4.6 oz) |
| 75 lb | 158 kcal | 178 g (6.3 oz) |
| 100 lb | 196 kcal | 220 g (7.8 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
- Peeled and sliced, or mashed into a puzzle toy.
- Frozen slices make a hot-weather treat.
- Skip banana bread and banana chips, which add sugar and fat.
