One of our dogs ended up to the vets with same problem he had stitches in it the nurse done a good job of doing the bandage good job all round went to bed next morning the bugger stripped off all the bloody bandage we was not too happy so we put a old sock on his foot over the dressing and again got it off we shouted at him STOP THAT and ended up wrapping masking tape around the sock and rubbing soap on it he still attempted to get off to he was ready for his stitches out
