I’m not sure about the green tops or stems but I’d probably remove them first. As with any fruit, you should only feed strawberries to your furry friend in small amounts. Even though dogs can eat strawberries in big amounts, large amounts of strawberries eaten by dogs can cause diarrhea in our main-pooch. You should NOT allow your dog to eat a strawberry plant if you have a strawberry patch in your backyard. The leaves are not harmful.
