Can Dogs Eat Bananas? Portions and Peel Questions

Bananas are generally considered safe for dogs, and many enjoy the taste and soft texture. They contain fiber and some nutrients, but they are also high in sugar. That makes them a treat, not a staple. Dogs with diabetes, obesity or a sensitive stomach need individual advice.

The peel is not considered poisonous, but it is tough and hard to digest, and a dog that swallows a lot of it can have a blockage or a bad stomach. Peel the banana and offer only the flesh.

As a guide, a few thin slices for a large dog and a slice or two for a small dog, no more than a couple of times a week. Too much banana can cause loose stools or constipation. Extras like this should stay a small part of the day's food. A common vet guideline is that treats and extras make up no more than about 10 percent of daily calories.

Skip banana bread, muffins, banana chips, and banana desserts. They contain sugar, fat, salt, and sometimes raisins, nuts or chocolate. Check any product for xylitol before sharing.

Bananas are higher in sugar and calories than many vegetables. For a small dog, a whole banana is a lot of calories in one go. A few slices spread through the week is a better pattern, especially for dogs with weight problems.

Dogs with diabetes should only have banana under vet guidance, since the sugar content can affect blood sugar.

Some owners use banana as a gentle food for upset stomachs, but there is no strong evidence it treats anything. Too much banana, with its fiber and sugar, can cause loose stools or constipation. Introduce it gradually, and if your dog has any ongoing digestive problems, ask your vet rather than relying on home remedies.

Slices can be mashed into a lick mat or frozen for a cooling treat. Plain frozen banana slices should be small enough to avoid choking.

• Mash a little banana on a lick mat.
• Freeze thin slices on a tray.
• Mix a spoonful into plain yogurt, if your dog tolerates dairy.
• Avoid the peel and any banana sweets.

For toy breeds, a single thin slice is a decent treat. Medium dogs can have a few slices, and large dogs a little more. A banana is a lot of sugar for a small dog, so a whole one is far too much in one sitting.

Because portion needs vary, use your dog's usual treat allowance as a guide. If your dog is on a weight plan, replace a normal treat with banana rather than adding it on top.

Puppies can have a tiny piece, but offer it once and wait a day before offering again. Senior dogs with kidney disease may need to limit potassium, and bananas are known for it, so ask your vet if your dog has kidney problems.

Dogs with diabetes should only eat banana under vet guidance. If your dog gets loose stools or vomiting after banana, skip it in future.

Owners often give a whole banana to a small dog, or let the dog have the peel. Another mistake is giving banana bread, which contains sugar, fat and sometimes raisins or nuts. A third is using banana as a daily snack, which adds a surprising number of calories over a week.

Some people mash banana into a toy and freeze it, which is a good idea in moderation. The risk is when the toy is also stuffed with peanut butter, so check the total calories in one go.

If your dog eats a whole banana with the peel, watch for vomiting, no stools and belly pain, and call your vet if you see them. A blockage is an emergency.
