Bananas Nutritional Facts At A Glance

If it’s not clear from the numbers, bananas are a great source of dietary fiber. They can help with digestive and gastrointestinal issues. Bananas are especially good for constipation, ulcers, and heartburn.

Bananas are a good source of Vitamin B6, biotin, and copper. They are also low in sodium. Plus, they are a wonderful prebiotic.

Vitamin B6 helps the body produce red blood cells; and it metabolizes carbs and fat to turn them into energy. It also removes unwanted chemicals from the kidneys and liver.

Here’s a little-known fact: from a botanical point of view, bananas are berries!

Can Dogs Eat Bananas?

Yes, dogs can eat bananas. There is nothing harmful about the fruit of the banana. In fact, some veterinarians recommend giving a dog a little banana if he’s having gastrointestinal problems.

If you slice them up they can be a good alternative to fatty or salty treats. Lots of dogs love bananas. (My dogs go crazy as soon as I peel a banana.)

You do need to be careful and not give your dog banana peels. They are not toxic but they are harder for dogs to digest. If your dog eats the banana peel he could vomit it back up in a few hours. In some cases a dog could develop a blockage from eating banana peels.

Are Bananas Good For Dogs?

Absolutely, yes! Along with the health benefits already mentioned, bananas can be a good prebiotic for dogs. Your dog’s gastrointestinal system contains a multitude of microorganisms to help him digest his food.

Most of these microorganisms (flora) are beneficial but some are not so good. Prebiotics can help the good microorganisms grow. Many dog foods add these prebiotics but you can give your dog foods like bananas a couple of times per week to encourage this friendly flora to grow in your dog’s gut.

How Much Banana Can (Should) Dogs Eat?

This is an important question. With all of their health benefits, bananas are still relatively high in natural sugars. You should only give your dog a moderate amount of banana – and not every day. A medium-sized dog could eat half a banana at one time; while a small dog could eat a quarter of a banana.

Too much banana at one time could pose a problem for dogs with diabetes so talk to your veterinarian before letting these dogs have bananas or other fruits high in sugar.

Too much banana for any dog can result in an upset stomach, which is true of eating too much of anything.

How Often Can Dogs Eat Bananas?

If your dog doesn’t have health issues that might be affected by the sugar in bananas, you could give him a moderate amount of banana two or three times per week.

The Correct Diet Is Important

Dogs need to eat the correct diet for good health. This means that they require good quality protein and fat. Foods like bananas should only be given as an occasional treat.

While there are many different ideas about good dog foods and different ways to feed dogs, your dog needs the following in his diet:

  • Good Sources of Protein- All dogs need good sources of animal protein in their diet. Meat, fish, poultry, and eggs are all good sources of animal protein.
  • Good Sources of Fat- Fat provides essential fatty acids (EFA) and helps distribute the fat soluble vitamins A, D, E, and K so your dog’s body can absorb them.
  • Named Ingredients- Look for named ingredients in your dog’s food and avoid generic ingredients. The more specific the ingredient is, the better. Otherwise, you don’t really know what you are feeding your dog.
  • Low to Moderate Carbohydrates- Many dog foods are loaded with carbohydrates. This is true even with some good quality foods. Carbohydrates are not “bad” and they can be beneficial (dietary fiber can come from carbs, for example). But carbs should not be a substitute for protein.
  • Avoid Artificial Preservatives, Colors, and Sweeteners- Artificial preservatives and colors/dyes have been linked to some health problems in humans and animals. You should try to avoid these ingredients in dog foods.
  • AAFCO- AAFCO is the Association of American Feed Control Officials. AAFCO sets voluntary standards for pet food labeling. Look for foods that have these minimum standards.
  • Fresh Water- All dogs need easy access to fresh water unless they are ill or have some other reason to be temporarily kept away from water.

What Are Other Health Alternatives To Bananas In A Dog’s Diet?

Bananas are a healthy treat but there are many other fruits and vegetables that can provide some of the same benefits. You should consider these foods as treats.

Check with your veterinarian if your dog has any health issues and you are concerned about giving any of these foods.

  • Apples
  • Asparagus
  • Bell pepper
  • Broccoli
  • Brussels sprouts
  • Carrots
  • Cauliflower
  • Cucumber
  • Green beans
  • Mangos
  • Oranges
  • Parsnip
  • Pears
  • Pineapple
  • Pumpkin
  • Strawberries
  • Summer squash
  • Sweet potato
  • Tomatoes
  • Zucchini
