Can Dogs Eat Banana?

SAFE

SAFE — Plain banana is generally safe for dogs in small amounts.

Peeled banana flesh is not toxic to dogs and is a common ingredient in homemade treats. It is relatively high in natural sugar, so keep servings small.

See our guide to fruits dogs can and can't eat to compare this with the rest of the fruit list.

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.

Fresh banana and dried banana are not the same treat. Banana chips and dried banana are generally not recommended: they are more concentrated, can swell if not chewed properly and may contribute to a blockage, and shop-bought chips often contain added sugar, oil, salt or preservatives. They are not toxic, but plain fresh banana is the better choice.

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.

Can Puppies Eat Banana?

Small amounts of mashed banana are commonly used as a puppy training reward, but puppies fill up quickly on extras.

Introduce it slowly and speak to your vet if your puppy is on a specific growth diet.

What If My Dog Ate Too Much?

Too much banana usually leads to a mild digestive upset or constipation rather than an emergency.

Offer fresh water and return to their regular food.

If your dog swallowed a whole peel, or is vomiting repeatedly, straining, lethargic or has a painful belly, contact your vet.

Apples

Apples can be an occasional treat for many dogs when served plain and properly prepared. They contain fiber and several nutrients, but they also contain natural sugar and should not replace a complete and balanced diet.
