Can Dogs Eat Bananas?

  • 10 min read

Bananas are a popular health fruit because they are full of nutrients. Plus they’re readily available, easy to carry around for a quick snack, and loaded with natural sugars. But are they great for sharing with your furry friends?

The good news is that bananas are safe for your dog. They’re a tasty treat that can provide dietary fiber, potassium, and other vitamins to your dogs. But you can go overboard as bananas also contain a lot of sugar. 

So what is the right serving size for your dog? And are there any other precautions you need to take while feeding bananas to your dog? You’ll find answers to these questions in this article.

5 Awesome Health Benefits of Bananas For a Dog

Let’s first start by discussing the nutritional value of bananas and how these benefit your dog's health:

1. Can Support Digestive Health

Bananas contain both soluble and insoluble fibers that are essential for your dog’s digestive system. The soluble fiber absorbs water and gets fermented in the large intestine. It helps add bulk to the stool thus reducing diarrhea.

Also, their fermentation produces short-chain fatty acids that prevent the growth of bad bacteria in the gut and helps increase the body’s ability to absorb minerals.

Insoluble fibers on the other hand help soften the dog’s stool by attracting water into the intestines and preventing constipation.

2. Provides Essential Vitamins 

Essentially bananas are rich in 3 types of vitamins - vitamin C, B6, and B7. All of which play a critical role in supporting your dog’s overall health.

Vitamin C is very important for your dog’s immune system as it supports the production of white blood cells that help the body fight against infection. Its also a powerful antioxidant that protects the cells against free radical damages, reduce inflammation and cognitive aging in dogs. 

And although a dog’s body can synthesize vitamin C on its own, various environmental reasons like stress, growth, injuries, vaccinations, or illnesses can lead to its depletion. In such cases, fruits like bananas can help dogs fulfill their daily nutritional requirements.

Vitamin B6 also serves an important role in your dog’s body as it’s responsible for the production of red blood cells and healthy brain function. It also supports glucose generation, hormone regulation, and immune response in dogs. And unlike vitamin C, a dog’s body cannot make its own vitamin B6, hence you need to feed them supplements like bananas.

The third vitamin that’s found in bananas is B7 more commonly known as biotin. It benefits your dog’s body from the inside to the outside. It promotes healthy skin and coat, proper muscle formation, and supports digestion by metabolizing proteins and fatty acids.

3. Rich Source of Potassium 

Bananas are loaded with potassium which is a primary electrolyte for dogs. It aids in the transmission of nerve impulses from the brain to the body. This exchange is critical as it controls a majority of body functions including heartbeats and contracting and relaxing of muscles.

Potassium also supports muscle growth, kidney function, and absorption of nutrients in your dog's body. Furthermore, it works with sodium to prevent dehydration and move water in and out of the cells.

Although the dry dog food that you feed your dog contains potassium, it might not be enough for your dog's daily requirements. Especially if you have a very active dog, they might need more potassium which they can get from bananas.

4. Loaded With Many Other Minerals

Apart from potassium, bananas also contain manganese, magnesium, and copper.

Manganese which is an essential trace mineral is required by a dog’s body to activate many enzymes that support bodily functions including energy production, fat and protein metabolism, bone development, and nerve function.

Magnesium which is found in bone and soft tissues is required for multiple metabolic functions in a dog’s body. It acts as an activator or catalyst for various enzyme systems including the one that transports energy within cells for metabolism and helps build protein. 

And lastly, copper aids in the absorption of iron and the formation of dogs' bones, collagen, and connective tissue. It also plays a major role in the creation of myelin, a membrane that protects the nerves in the dog’s body.

5. Aids in Weight-loss

The fat content of bananas is very low, thus making them a perfect treat for your dog. You can feed it instead of other fatty and salty foods to manage their weight. 

How to Feed a Banana to a Dog?

Now that you know all the potential benefits of feeding bananas, let’s move on to discussing the right ways to feed bananas to a dog. 

The Right Portion Size

The first few questions that’ll come to a pet owner's mind are how many bananas can dogs eat and how often can dogs eat a banana?

Truth be told, even though bananas are loaded with nutrients and fiber, overfeeding them can lead to various health issues like upset stomach or diarrhea due to the extra fiber content. Natural sugar can also pose a problem if eaten in large quantities. 

It’s important that you use bananas as a treat that you serve in between meals. It should never replace their healthy and well-balanced meal.

Now to decide the right amount of bananas you can feed your dog, you should take into account various factors like their age, breed, weight, and existing health conditions. A general guideline is to offer up to half a banana to a large dog and 2-3 slices to smaller dogs.

Talking about the frequency, it’s safe to feed a dog bananas every day. But that could increase their fiber intake and blood sugar levels, so try sticking to 2-3 times a week only. You can alternatively switch between bananas and other healthy treats.

You can also follow the 90/10 rule here by making sure 90% of their daily calorie intake comes from a complete and balanced diet and 10% from treats like bananas.

If your dog suffers from sensitivities or other health conditions, consult with a veterinarian before feeding them bananas.


Can Dogs Eat Banana Peels?

No, you shouldn’t feed banana peels to your dog. Even though they’re nontoxic, they contain too much fiber that can be hard to digest and cause an upset stomach. Plus the thick skin can cause an internal blockage. 

If your dog accidentally eats the banana peel, they might experience vomiting or distress. In such cases, get in touch with your veterinarian just to be on the safe side.

Bananas for Puppies

Bananas are safe for puppies. You can feed them 2-3 slices of bananas a few times a week. But remember that puppies usually have a special diet that is made to support their growth. So chances are they are getting the nutrients that are available in a banana from their regular meal. 

Hence, it would be ideal to first check with your veterinarian if you wish to add bananas to your puppy’s diet.

Safe Ways of Feeding Bananas to a Dog

There are a few different ways in which you can safely feed bananas to your dog. But before discussing those, let's talk about the ripeness of bananas and what's the best stage to feed them.

1. Unripe or Green Bananas

The unripe bananas contain a high amount of resistant starch and low sugar content. If your dog suffers from diabetes, you can feed them unripe bananas. But the high amount of starch can make it a little hard to digest. 

There’s also a chance that your dog might not like the taste of green bananas as they taste a little bitter.

2. Ripe or Yellow Bananas

This is a preferable option for dogs because a ripe banana is easier to digest as the resistant starch gets converted to simple sugar. It's also a rich source of potassium and contains many other essential vitamins and minerals. All of which can be beneficial for your dog's health. 

3. Overripe or Brown Bananas

An overripe banana contains many antioxidants that can help your dog fight inflammation but it also contains high sugar content that can be harmful to your dog especially if they have any preexisting health condition like diabetes. 

Banana Recipes for Dogs

1. Mix With Other Food Items

Bananas can be easily mashed and mixed into any food item. Some pet owners like to add it to their dog’s daily meal, while others like to mix it with dog-friendly peanut butter or yogurt to serve as a treat.

4. Banana Bread

Banana bread made for human consumption contains a lot of butter, sugar, raisins, and vanilla extract, all of which can be harmful to a dog.

Also if your dog is suffering from certain health conditions you might want to consult with a veterinarian before making any changes to their diet.
