Frequently asked questions
Can dogs eat banana peels?
Better not. The peel is fibrous, hard to digest and can carry pesticide residue. If your dog eats a piece, it's usually harmless. If there's vomiting or constipation, call your vet.
How much banana can my dog eat a day?
Rule of thumb: snacks should make up no more than 10% of daily calories. For a normally active 10 kg dog, that's about 80 g of banana, or roughly two thirds of a medium-sized fruit. The calculator above shows the amount for your dog's weight.
Can puppies eat bananas?
Small pieces are usually fine. But puppies need precisely balanced food for growth, so keep snacks especially sparing.
Do bananas help with diarrhea?
Mashed banana is often mentioned as a home remedy because it contains pectin. If the diarrhea lasts longer than a day or there's blood in the stool, your dog needs to see the vet.
Can dogs eat banana chips?
Only unsweetened and rarely. Store-bought chips are often sugared or fried and have many times the calories of fresh banana.
