Growing up our dogs favorite day was when the farrier would come out. They loved gnawing on/eating the trimmed hoof pieces. When we sold the farm and started boarding our horses we'd sometimes save the hoof trimmings for the dogs, and they went nuts for them! I was at the barn the other day and thought about taking home a bit of hoof for Milly, but wasn't sure how safe this is, or if it would be bad for her. Anyone with horses let their dogs eat the hoof trimmings? Can it make them sick or upset their tummies? The only thing I really remember about feeding them, other than the dogs loving them, is they made their breath smell bad.
