Can Dogs Eat Bananas? In Moderation

Why it’s fine in small amounts

Banana flesh is not toxic to dogs. It provides potassium, vitamins B6 and C, and some fiber, and most dogs love the taste and soft texture.

The catch is sugar and calories. Bananas contain natural sugar and can add excess calories, so they should be an occasional treat and not an everyday snack or part of the main diet. Too much banana too quickly can cause digestive upset or weight gain. Ask your vet first if your dog is overweight or has a condition such as diabetes.

The peel is not toxic to dogs, but it is difficult to digest, so always peel the fruit first. Choose plain fresh banana, not banana bread or anything with added sugar, nuts or sweeteners.

Benefits

Soft and easy to mash, useful for smearing onto a lick mat
Provides potassium, vitamin B6 and vitamin C
Contains some fiber

Risks

Natural sugar and calories add up quickly
Peel is difficult to digest
Too much too quickly may cause digestive upset

How to serve it safely

Peel the banana and cut it into bite-sized pieces, or mash a little onto a lick mat. Keep all treats to no more than 10% of your dog's daily calories.

Small dogs: a couple of thin slices
Medium dogs: a few slices
Large dogs: a few more slices, not a whole banana every day

The right amount depends on your dog's size, age, weight and overall diet. Frozen pieces are a refreshing treat in warm weather.

If your dog already ate it

A bite of banana is no concern. If your dog ate a lot, expect a possible upset stomach. If your dog swallowed a whole peel or a large piece, watch for repeated vomiting, belly pain, loss of appetite, or no stools, and call your vet promptly because these can signal a blockage.

Do not try to induce vomiting at home. In the US you can also call ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (fees may apply); elsewhere, contact your local emergency vet.
