once in a while my puppy who is 7 months old ,drags his behind on the rug.i have checked for worms when he goes and does his job but i cannot see any.
We see this in dogs when the anal glands are impacted. I recommend that you have your pet checked by the vet when this happens so the vet can express the glands. In some cases the glands can become infected so have it checked out. vetcare
