I've notices my dog, since she was a puppy scoot around on her butt sometimes after going poop.  She just had her anal glands squeezed last month at the vets, (never had it done before) the vet just did it.  She seems to be scooting and spinning on her butt thing. Doesn't this seem to soon for her to need them to be squeezed again? Anyone have any experience with this?
