Can dogs eat bananas?

Yes — in moderation

Yes. Bananas are safe for dogs in small amounts and are a sweet, natural treat. High in sugar, so don't overdo it.

The full picture

Bananas are a popular dog treat because they're sweet, soft, easy to portion, and well-tolerated by most dogs. They're a good source of potassium, vitamin C, vitamin B6, and fibre. The main caveat is sugar content — bananas are naturally high in natural sugars, so they should be a treat rather than a daily food. The skin isn't toxic but is hard to digest and can cause blockages, so always peel. Frozen banana slices make an excellent summer treat.

Safe portion size

A few small slices for a small dog, half a banana for a large dog, 2-3 times per week.

And while you're thinking about what's good for your dog, keeping on top of flea and parasite prevention is just as important as diet.
