Banana: Yes, in moderation
Safe — high in potassium but feed in moderation.
Bananas are a great source of potassium, vitamins, biotin, fiber, and copper. They are low in cholesterol and sodium. However, they are high in sugar, so they should be an occasional treat rather than a daily snack.
For medium dogs (20–60 lbs)
Half a banana a few times a week is a healthy treat.
