Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Bananas are safe for dogs and provide potassium, vitamins, biotin, and fibre. However, they are high in natural sugar, so they should only be given as an occasional treat, not a regular part of the diet. Too many bananas can cause constipation or upset stomach. Do not give your dog the banana peel — while not toxic, it is difficult to digest and could cause a blockage. Mashed banana can be mixed into a Kong or used as a training treat.
What You Should Know
While bananas is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
