Unfortunately, not every dog will enjoy bananas. Just like with humans, all dogs will have varying food preferences.
A good rule of thumb to go by is that a large dog can eat only up to half of a banana a day, while a small dog can have 2-3 small pieces per day.
If your dog has eaten too much banana you might notice that it appears your dog has a stomach ache.
Banana peels are not toxic to dogs, but they do contain a lot of fiber and can be very difficult for your dog to digest.
