Quick answer

Yes, dogs can eat bananas in small amounts. Peeled banana is a healthy occasional treat with potassium, fibre, vitamin B6 and vitamin C. It's high in sugar, though, so give a few thin slices, not a whole banana, and keep treats to no more than 10% of daily calories. Never give the peel, and skip banana chips and banana bread.

Are bananas good for dogs?

Bananas give dogs potassium, fibre, vitamin B6, vitamin C, magnesium and biotin. Because they're low in fat and salt, some vets suggest a little banana instead of fatty commercial treats.

The catch is sugar. Bananas are naturally sweet, so they're a treat to give occasionally, not a daily snack, and they should never replace a balanced dog food.

How much banana can a dog eat?

Keep all treats, banana included, to no more than 10% of your dog's daily calories. A whole banana is too much for most dogs, especially puppies and small breeds. These amounts are a daily maximum for a healthy adult dog, using slices about ¼ inch (6 mm) thick.

Can dogs eat banana peels?

No. Banana peels aren't toxic, but they're very hard to digest. A peel can cause stomach upset or even an intestinal blockage, and it may carry pesticide residue. Always peel the banana first.

If your dog has eaten a peel, watch for vomiting, loss of appetite, tummy pain, weakness, constipation or diarrhoea, and call your vet if you see any of them.

Easy ways to serve banana

  • Fresh slices as a training reward or snack.
  • Mashed on top of food as an occasional topper.
  • Frozen in a stuffable toy: mash banana, fill the toy, freeze it, and you have a long-lasting treat.
  • With a little peanut butter, but only peanut butter that contains no xylitol.
  • Frozen bite-sized pieces on a hot day; cut them small to avoid choking.
  • Blended with plain yogurt that has no added sugar and no xylitol.

Banana products to avoid

  • Banana chips and dried banana. They can swell if swallowed without much chewing and contribute to a blockage, and they often contain added sugar, salt or preservatives.
  • Banana bread. It may contain raisins, xylitol or nutmeg, all of which can harm dogs.
  • Banana pudding and desserts. Too much sugar and other unsafe ingredients.
  • Whole frozen bananas. A choking and blockage risk; cut them up first.

Bananas also aren't a home treatment for diarrhoea. If your dog has an upset stomach, ask your vet what to do.

Can puppies eat bananas?

Yes, in smaller portions than adult dogs. Offer one thin slice, introduce only one new food at a time so you can spot what caused any upset, and keep it occasional.

Frequently asked questions

Are bananas safe for dogs?

Yes, peeled bananas are safe for most dogs in small amounts. True banana allergies are uncommon, but some dogs get an upset stomach, so start with one slice.

How much banana can I give my dog?

From 1–2 thin slices a day for very small dogs up to half a banana for giant breeds, keeping all treats under 10% of daily calories. A whole banana is too much for most dogs.

Can dogs eat banana peels?

No. Peels aren't toxic but are hard to digest and can cause an intestinal blockage. Always remove the peel.

Can dogs eat frozen bananas?

Yes, in small pieces. A whole frozen banana can be a choking and blockage risk, so cut it into bite-sized pieces first.

Can dogs eat banana chips?

It's best not to. Dried banana chips can swell and contribute to a blockage, and they often contain added sugar, salt or preservatives.

Do bananas help dogs with diarrhoea?

Don't use bananas to treat diarrhoea at home. If your dog has diarrhoea, especially with vomiting, blood or weakness, contact your vet.
