Dogs can eat bananas. Bananas for dogs can have a laxative effect, so you can occasionally give them some bananas, but you can’t eat too much at one time. If they are puppies, it is best not to eat them first. Because puppies’ intestines and stomachs are relatively fragile and sensitive, they may suffer from indigestion and other reactions after eating. In addition to bananas, dogs can also eat apples, watermelons, blueberries, strawberries, pears, etc., but the cores cannot be given to dogs.
