We have a huge Mullberry tree in the back yard. All the little delicious berries are ripe this time of year. Every day when I let my dog out he runs straight to the Mulberry tree and will graze under it, eating the fallen berries as long as I let him. I don't think it is causing any problems. I've seen no diarrhea or vomiting. Has anyone ever heard of a dog doing this before? And do y'all think it is okay?
