How much banana can dogs eat?

Quick Answers

Dogs can eat bananas in moderation. Bananas are a healthy, low-calorie treat for dogs. Most experts recommend limiting bananas to a few small pieces per day due to their high sugar content. Too many bananas may cause constipation, diarrhea, or upset stomach in dogs. Always introduce new foods slowly and watch for any signs of an allergic reaction. Consult your veterinarian if you have any concerns about feeding bananas to your dog.

Are Bananas Good or Bad For Dogs?

Bananas are good for dogs in moderation. Bananas are a healthy food for dogs because they contain essential vitamins and minerals that dogs need, such as potassium, vitamin B6, vitamin C, fiber, and manganese. Bananas are low in sodium and cholesterol, which makes them a healthier treat option than many human foods.

However, bananas do contain a lot of natural sugar. The main type of sugar found in bananas is fructose. While fructose is healthier than processed sugars, too much can still negatively impact a dog’s health. That’s why it’s recommended to only feed dogs bananas as an occasional treat in small amounts.

Benefits of Bananas for Dogs

  • Good source of potassium – maintains fluid balance
  • Fiber – promotes digestive health
  • Vitamin B6 and C – supports immune system health
  • Manganese – aids bone development
  • Antioxidants – protects cells from damage
  • Low sodium and cholesterol

Potential Risks of Too Many Bananas

  • Weight gain – bananas are higher in natural sugars and calories
  • Too much fiber – may cause constipation or diarrhea
  • Digestive upset – vomiting, gas, bloating
  • Tooth decay – natural sugars can damage teeth

How Many Bananas Can Dogs Eat?

There is no single definitive answer on how many bananas a dog can safely eat. Experts tend to recommend limiting bananas to a few small pieces per day as an occasional treat.

The amount of banana you can feed your dog depends on your dog’s size, activity level, health status, and overall diet. Large active dogs can generally tolerate more banana than small dogs or senior dogs. Dogs at a healthy weight need less high-calorie treats than dogs needing to gain weight.

As a general guideline, here are some recommended maximum amounts of banana to feed dogs per day:

  • Small dogs: 1-2 small pieces (up to 1/4 of a standard banana)
  • Medium dogs: 1-2 average sized pieces (up to 1/2 a banana)
  • Large dogs: 2-3 large pieces (up to 1 whole banana)
  • Puppies: No more than 1-2 very small pieces, mashed

It’s always best to start with less and gradually increase to observe your dog’s tolerance. Be sure to reduce other treats in your dog’s diet if adding banana.

Nutritional Content of Bananas for Dogs

Here is the nutritional content of an average medium-sized banana:

Nutrient Amount % Daily Value for Dogs*
Calories 105 5%
Fat 0.4g 1%
Sodium 1mg 0%
Potassium 422mg 12%
Carbs 27g 10%
Fiber 3g 12%
Sugar 14g n/a
Vitamin B6 0.5mg 25%
Vitamin C 10mg 17%
Manganese 0.3mg 15%

*Based on daily nutritional needs for a 25lb dog. Needs vary by size and age.

As you can see, bananas provide many beneficial vitamins, minerals, and fiber to dogs while being low in fat and sodium. However, their high sugar content means they should only be an occasional treat.

Can Puppies Eat Bananas?

Yes, puppies can eat bananas in small amounts. Bananas provide key nutrients puppies need for growth and development, like vitamin B6, vitamin C, potassium, and manganese.

However, puppies have more sensitive digestive systems than adult dogs. It’s best to wait until puppies are around 3-4 months old before introducing small amounts of banana.

To serve bananas to puppies:

  • Start with just a tiny piece mashed up
  • Gradually work up to 1-2 very small pieces daily
  • Monitor for any diarrhea or upset stomach
  • Discontinue use if any negative reaction

It’s best to minimize sugar in puppy diets, so banana should be reserved for occasional treats. Feed other healthy options like cooked chicken, yogurt, pumpkin, or carrots more frequently instead.

Can Dogs Eat Banana Peels?

No, dogs should not eat banana peels. While banana peels are not toxic, they are difficult for dogs to digest properly. Banana peels could cause a potential choking hazard or intestinal blockage risk.

Signs of intestinal blockage from banana peels may include:

  • Vomiting
  • Diarrhea
  • Constipation
  • Loss of appetite
  • Lethargy
  • Abdominal pain

If you notice any of these symptoms in your dog after eating a banana peel, contact your veterinarian immediately. Intestinal blockages can become life threatening if left untreated.

For safety, be sure to peel bananas before giving them to dogs. Discard peels in the trash or a compost bin where dogs cannot access them.

Can Dogs Eat Bananas Every Day?

It’s not recommended to feed dogs bananas every day. Bananas should be given just a few times per week as an occasional treat.

Daily banana consumption may lead to:

  • Weight gain – bananas are high in natural sugar and calories
  • Digestive issues – especially for smaller dogs
  • Diarrhea – from too much fiber
  • Tooth decay – sugar can damage tooth enamel over time

Moderation is key when feeding bananas to dogs. Restrict banana pieces to no more than 10% of your dog’s daily caloric needs. Too many bananas can unbalance healthy dog nutrition.

Other fruits and vegetables, like apples, blueberries, carrots, and green beans can provide similar benefits to bananas without as much sugar. Rotate different fresh produce for variety.

Can Diabetic Dogs Eat Bananas?

Bananas may be safe for diabetic dogs in very small amounts, but they should be limited. Uncontrolled diabetes can seriously endanger a dog’s health.

Bananas have a high glycemic index, meaning they cause a rapid rise in blood sugar. While the natural sugars in bananas are healthier than processed sugars, they can still negatively impact blood glucose control in diabetic dogs.

It’s best to avoid feeding bananas to diabetic dogs unless approved by your veterinarian. Opt for low glycemic fruits like berries instead. Monitor blood glucose carefully after any new food.

Work closely with your vet to develop the best dietary plan for managing your diabetic dog’s condition.

Can Dogs Eat Bananas If They Have Diarrhea?

Bananas are not recommended for dogs with diarrhea. The high fiber content found in bananas may worsen diarrhea symptoms.

Instead, the BRAT diet is recommended to help firm up stools. BRAT stands for:

  • Bananas
  • Rice
  • Applesauce
  • Toast

However, bananas should be avoided for dogs with diarrhea. The high fiber can overstimulate the intestines. Stick to the rice, applesauce, and toast options when following the BRAT diet.

If your dog has diarrhea lasting more than 24 hours, call your vet. Dehydration from diarrhea can become dangerous without proper treatment. Your vet can recommend medication to help resolve diarrhea and gastrointestinal upset.

What Other Fruits Can Dogs Eat?

In addition to bananas, some other fruits dogs can eat include:

  • Apples – Good source of vitamin A & C. Remove seeds and core first.
  • Blueberries – Full of antioxidants. Choose fresh or frozen over dried.
  • Strawberries – Provide vitamin C and manganese. Limit due to higher sugar.
  • Cantaloupe – Packed with vitamin A & C. Avoid rind.
  • Watermelon – High water content. Remove seeds first.
  • Pumpkin – Helps digestive health. Use plain, not spiced for flavoring.
  • Cranberries – Offer antioxidant and vitamin C benefits. Choose low-sugar versions.

Fruits to avoid giving dogs include grapes, raisins, cherries, citrus fruits, and any pits/seeds, which can cause intestinal obstruction and other serious harm if consumed.

Always introduce new fruits slowly in small amounts. Monitor for any signs of an allergic reaction or sensitivity.

Can Dogs Have Bananas With Peanut Butter?

Dogs can eat bananas and peanut butter together in small amounts. Some ways to serve bananas with peanut butter for dogs include:

  • Spread peanut butter over small slices of banana.
  • Slice a banana into coins and freeze, then coat frozen coins with peanut butter.
  • Mix a spoonful of peanut butter into mashed ripe banana.
  • Fill a Kong toy with peanut butter and top with banana slices.

When combining banana with peanut butter, reduce the amount of each to control calories. No more than 2-3 small spoonfuls total of peanut butter, and just 1-2 small banana slices for a medium dog. Only offer occasionally, not daily.

Be sure to only choose all-natural peanut butters without xylitol, as xylitol is extremely toxic for dogs.

Signs of a Banana Allergy in Dogs

It’s quite rare, but some dogs may be allergic to bananas. Signs of a banana allergy can include:

  • Itchy skin, hives, rash
  • Swelling of face, lips, eyelids
  • Vomiting
  • Diarrhea
  • Wheezing
  • Runny nose, watery eyes

If you notice any reaction after feeding bananas, stop giving them immediately. Severe allergic reactions can become life-threatening, so contact your vet right away if your dog displays signs like facial swelling or difficulty breathing.

To help prevent allergies, introduce bananas slowly in very small amounts. Some dogs have pollen-fruit syndrome and may react to fresh bananas but not frozen or heated banana.

Can Dogs Eat Banana Bread or Banana Chips?

It’s best to avoid feeding your dog banana breads, muffins, or chips. These banana products contain added sugar and fat that dogs don’t need.

Some additional risks of banana bread and chips for dogs include:

  • Excessive calories leading to obesity
  • Toxic additives like xylitol in baked goods
  • Choking hazards from chips getting lodged in throat
  • Intestinal upset from artificial ingredients, spices

If you want to share a banana treat with your dog, stick to small bites of plain banana rather than products with added ingredients.

Are Banana Peels Safe for Dogs?

No, dogs should avoid eating banana peels. The peels can be tough to pass and pose a choking risk or intestinal blockage. Signs of trouble after ingesting a banana peel include vomiting, diarrhea, abdominal pain, constipation, or loss of appetite. Never purposefully feed banana peels to dogs. It’s always safest to remove the peel before sharing a banana with your dog.

How to Serve Bananas Safely to Dogs

Follow these tips for safely serving bananas as an occasional treat:

  • Start with a small piece – no more than 1/4 of a banana
  • Mash thoroughly for puppies or older dogs
  • Mix in a little plain yogurt or peanut butter for flavor
  • Always peel first – never feed the peel
  • Cut slices lengthwise to prevent choking
  • Monitor stool consistency when first introducing
  • Don’t exceed recommended serving sizes

Are Bananas Good for Dogs?

Yes, bananas are good for dogs in moderation. Bananas provide key nutrients and are a healthier treat than many other options. Feed bananas as an occasional treat in small amounts. Limit to a few times per week to prevent negative health impacts in dogs.


Bananas make a great supplemental treat for dogs as part of a balanced diet. Their high fiber and antioxidant content provides digestive and immune health benefits. However, their high sugar content means bananas for dogs should only be fed occasionally and in limited quantities to avoid adverse effects.

When fed responsibly in moderation, bananas can be a tasty way to provide extra nutrition and enrichment to your dog’s routine. Work with your veterinarian to determine the ideal amount of banana to incorporate into your own dog’s unique nutritional needs and health goals.
