Sometimes it takes a while for medicine to work in animals, but if you are terribly concerned, as I would be, then I suggest that you take the pup to another vet and see if there is something else going on, like an allergic reaction to the medicine he is taking. Hope this helps, and best of luck to you and the pup.
