7 Benefits of Bananas for Dogs

Can i give my dog bananas

Can dogs eat bananas and get the same health benefits as humans do?

Yes – just as bananas are beneficial for the human diet, this fruit can help dogs in a variety of ways.

From digestion to energy levels, bananas for dogs have been proved to be an excellent superfood to add to your pet's diet on a weekly basis.

1. Vitamins B6 and C in bananas strengthen multiple systems.

Vitamin B6 (Pyridoxine) in bananas helps dogs to fight anemia and produce hormones, proteins, and neurotransmitters.

Vitamin C (Ascorbic acid) in bananas is an important nutrient for collagen and cartilage synthesis in dogs. It also strengthens a dog’s immune system and combats degenerative conditions.

2. Biotin (Vitamin B7) treats the outside of the dog.

Bananas are loaded with biotin, a vitamin that helps maintain shiny, healthy hair and skin in dogs, according to some studies.

3. Fiber in bananas helps relieve gastrointestinal symptoms.

The extra fiber in bananas can help ease a dog with an upset stomach and bring regularity to bowel movements, according to research.

4. Bananas are a prime source of magnesium.

Magnesium that bananas are full of promotes bone growth in dogs, and assists the canine's body in absorbing vitamins and producing protein, according to vets.

5. Bananas provide natural energy boosts.

The natural sugars found in bananas metabolize rapidly for a significant boost of energy, which is especially useful for athletic and active dogs, and has been proven in studies.

6. Bananas keep dogs in shape.

Bananas make much better dog treats than many of the fatty, salty foods owners like to give, thus they contribute to weight loss and leanness, as many vets have noted.

7. Bananas contain potassium, a vital mineral for body function.

Bananas have tons of potassium which replaces lost electrolytes in a dog's body, and strengthens dog's muscle development, and keeps blood vessel function in order, according to research.

So, can I give my dog bananas?

The answer is yes – you can give bananas for your dog, and there are many potential health benefits dogs can reap from eating bananas. Just make sure that you feed banana to your dog in moderation.

Adding an appropriate amount of banana to a dog’s daily diet can result in most if not all of the above mentioned benefits, some of which have been observed in studies.

Bottom Line: Bananas are safe for dogs to eat. However, since many dogs love the taste of bananas, it's important not to overfeed them.

4 Potential Side Effects of Bananas for Dogs

Side effects of bananas for dogsCan dogs eat bananas with no side effects? The answer is that unless ingested in excess amounts, there are no side effects of giving bananas to dogs.

So even though dogs can eat bananas and they provide excellent nutritional benefits, their health benefits apply only when given in suitable amounts.

Too much of anything is never good, but for dogs, too much bananas added to the diet can cause gastrointestinal discomfort, and in some rare worst-case scenarios, death.

Dogs who eat a large amount of bananas may experience any of the following conditions:

1. Weight gain.

An excess of bananas in a dog’s diet may lead to weight gain, particularly in sedentary dogs who don't burn off the excess amount of calories (source).

The high carbohydrate content in bananas as a result of many natural sugars creates a risk of weight gain in less active dogs, including those who are ill or elderly.

2. Do bananas give dogs diarrhea?

When giving too many bananas for dogs, constipation, gas, bloating, diarrhea, and vomiting may result from the ingestion of too much fiber and potassium (source).

3. Blood glucose issues.

Because of the surfeit of natural sugars in bananas, feeding too many bananas to dogs can lead to them having blood sugar irregularities (source).

4. Hyperkalemia.

Another potential side effect of giving bananas for dogs is hyperkalemia (source).

It occurs due to high concentration of potassium in the dog's blood. This condition may lead to heart problems and cardiac arrest in canines.

Symptoms of hyperkalemia include disorientation, weakness, and collapse.

Bottom Line: Fed as an occasional, healthy treat, bananas are good for dogs. However, when giving this fruit to dogs in excess, it may distress a dog’s body and even be fatal.

2 Safety Precautions

Safety precautions of bananas for dogsAre there any safety precautions to consider when giving bananas to dogs?

Even though there are no side effects of bananas for dogs when feeding in moderation, those asking themselves, can I give bananas to dogs, should keep the following precautions in mind.

If you give your dog bananas, steer clear of banana peels.

The fruit of the banana itself can be good for dogs, but what about the peel?

Some dog owners think that banana peels can be a good natural chew for their dog, but the problem is peels pose potential dangers to dogs.

Simply stated, banana peels are a form of roughage that can cause more trouble for a dog than they are worth.

Here are the two reasons why banana peels should be avoided at all costs:

1. Banana peels can cause blockages.

Because banana peels are hard to chew and to digest for dogs, they may become lodged in a dog’s throat or stomach.

2. The extra fiber in the peels can result in vomiting and constipation.

Banana peels are rife with fiber, and too much fiber can wreak havoc in a dog’s digestive system. Giving banana peels for dogs may cause them to vomit or suffer from constipation.

Can Dogs Eat Bananas? Summary

Can Dogs Eat BananasIn conclusion, dogs can definitely eat bananas and bananas are not toxic to dogs.

Given as a treat in small quantities, bananas can be very beneficial for dogs in a variety of ways and may provide several health benefits for canines.

Be sure to contact a veterinarian if you are concerned that your dog has ingested too much banana or banana peels.

For a healthier snack, consider switching out sugary dog treats with a frozen slice of banana, and remember to feed dog treats with restraint and reasonableness.
