Yes, dogs can eat bananas safely in moderation. Bananas are non-toxic to dogs and contain beneficial nutrients like potassium, vitamin B6, vitamin C, fiber, and magnesium, which can support muscle, bone, and overall health. However, due to their high sugar content, bananas should be given only as an occasional treat and not as a regular part of the dog's diet. The banana peel is not toxic but is hard for dogs to digest and may cause digestive upset or blockage, so it is best to feed peeled bananas. Portion size depends on the dog's weight, and treats including bananas should constitute no more than 10% of the dog's daily caloric intake to avoid problems like weight gain or stomach upset. Bananas can be served fresh, sliced, or even frozen, but always in small amounts. If any digestive symptoms occur after feeding bananas, consulting a veterinarian is advised. In summary, bananas are a safe and healthy occasional treat for dogs if given peeled and in moderation, considering the dog's size and overall diet balance.
