Can dogs eat bananas? Yes, in moderation
By the Photoshoot Pets team · Updated November 1, 2026
Your toddler waved half a banana in the air for one second too long, and now the dog has it and the toddler is furious. Or maybe you’re just peeling one for breakfast while a nose rests on your knee. Either way: dogs can eat bananas. They’re sweet, soft and most dogs love them. The trick is keeping it to a few pieces.
Are bananas good for dogs? Sweet, so go easy
Bananas have potassium, vitamin B6, vitamin C, fiber and magnesium. Some vets suggest them as a swap for treats that are high in fat or salt. They’re also soft, so they work for older dogs with tired teeth and for pill hiding, which every dog owner eventually needs.
The catch is sugar. Bananas are one of the sweeter fruits you can share, and they’re higher in calories than a crunchy vegetable. A dog who gets banana every day can pick up extra weight without anyone noticing. So bananas are a sometimes treat, not a daily one.
Which banana bits are safe?
| Banana | Okay? | Why |
|---|---|---|
| Fresh banana, peeled and sliced | ✅ Yes | Soft and sweet. Small slices only. |
| Frozen banana slices | ✅ Yes | A cold treat on a hot day. Keep the pieces small. |
| Mashed banana in a chew toy | ✅ Yes | A thin smear goes a long way. |
| Banana peel | ⚠️ Avoid | Not toxic, but hard to digest and can cause a blockage. |
| Dried banana chips | ⚠️ Avoid | Often fried and sweetened. Very sugary. |
| Banana bread, muffins, pudding | ❌ No | Sugar and fat, and some recipes have nuts, chocolate or raisins. |
| Banana with chocolate | ❌ No | Chocolate is toxic to dogs. |
| Sugar-free banana desserts | ❌ No | May contain xylitol, which is toxic to dogs. |
How much banana can a dog have?
Treats of any kind, banana included, should stay under about 10% of your dog’s daily calories. Because bananas are sweet and fairly calorie-dense for a fruit, that limit comes up faster than you’d think.
- Small dogs: one or two thin slices.
- Medium dogs: a few small slices.
- Large dogs: several small slices.
Keep it to a couple of times a week. If your dog is diabetic, overweight or on a prescription diet, ask your vet before sharing at all, since the sugar adds up.
What about the peel?
Banana peels aren’t toxic to dogs, but they’re tough and fibrous, and dogs don’t digest them well. A small chewed bit might just mean an upset stomach. A whole peel swallowed in a hurry can cause an intestinal blockage, especially in a small dog.
The usual way this happens is the kitchen trash or a peel left on the counter. If your dog is a bin raider, put the peels somewhere they can’t reach and always peel bananas before sharing.
Banana chips and baked goods
Dried banana chips sound like a healthy snack, but a lot of them are fried in oil and coated in sugar or honey. That’s a lot of sugar in a small, crunchy piece. If you want to share dried banana, look for plain, unsweetened dried banana and give only a piece or two.
Banana bread and muffins are worse. Beyond the sugar and butter, recipes often include walnuts, chocolate chips or raisins. Raisins and chocolate are toxic to dogs, and so are macadamia nuts. Some “healthy” or sugar-free recipes use xylitol. Keep baked goods off the counter edge.
Are bananas good for an upset stomach?
You’ll hear this one a lot. Bananas have fiber, and some people offer a bit of plain banana to a dog with mild tummy trouble. It can be gentle, but it isn’t a fix, and too much banana can make loose stools or constipation worse. If your dog has diarrhea or vomiting that lasts more than a day, shows up with lethargy or blood, or happens in a puppy or senior, skip the home remedies and call your vet. A banana won’t hurt in a small amount. It just shouldn’t stand in for getting them checked.
When to skip bananas
- Diabetes: the natural sugar can affect blood sugar.
- Weight loss plans: crunchy vegetables are a lighter swap.
- Constipation or an upset stomach: too much banana can make digestion worse, not better.
My dog ate a banana peel. What now?
Most of the time, a dog who eats part of a peel ends up with a grumpy stomach and nothing more. Watch them for the next day or two. Call your vet if you see repeated vomiting, a sore or swollen belly, straining to poop, or a dog who won’t eat. Those can be signs of a blockage. If your dog got into banana bread or muffins, check the recipe or packaging for raisins, chocolate, nuts or xylitol, and call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 if any of those were in it.
