Most of ours eat bananas (along with a range of fruit and veg)
Oscar used to love them though and given the opportunity would eat them skin and all!
They're high in potassium and therefore good for dogs with colitis (which Oscar had) so I always use them as treats.
We live near a primary school and one day Oscar found a banana stuffed into a bush near the school (presumably rejected from a lunchbox
). He was so pleased and from that day on, despite his arthritis and wonky hips, would run to the same bush.
