The full answer
Banana flesh contains nothing that is known to be toxic to dogs, and it is soft, easy to portion and easy to mash into homemade treats.
Because banana is comparatively high in sugar for a fruit, it suits occasional treating rather than daily feeding — particularly for dogs that are overweight or have conditions affecting blood sugar.
Is Banana Good for Dogs?
Banana provides fibre, potassium and vitamin B6, and it is low in fat and sodium.
It is not a substitute for a complete diet, and dogs on balanced commercial or vet-formulated food already receive these nutrients.
Potential benefits
- Soft texture works well for older dogs and for stuffing food toys
- Low in fat and sodium
- Mashes easily into homemade treat recipes
- Freezes well for a longer-lasting treat
Risks and Things to Know
- Higher in sugar than most fruits — not ideal for overweight or diabetic dogs
- Banana peel is not toxic but is tough and fibrous and can cause a blockage or vomiting
- Large amounts can cause constipation or an upset stomach
- Banana-flavoured products may contain xylitol or other unsuitable ingredients
How Much Can Dogs Eat?
A couple of small slices is plenty for most medium-sized dogs; very small dogs need noticeably less.
Appropriate amounts depend on your dog's size, diet, weight and health. Ask your vet if your dog is diabetic, overweight or on a prescription diet.
Keep all treats combined to a small share of daily calories.
How Should I Prepare It?
- Always remove the peel.
- Slice into bite-sized pieces, or mash for puppies and older dogs.
- Freeze slices for a slower, cooling treat.
- Never add chocolate, honey-nut spreads, or sweetened yoghurt.
