A. I am not sure how old your dog is now, or how long ago you dewormed him but usually (and depending on what type of medicine was given) pups may be on a deworming schedule involving a few treatments, spaced out over several weeks. It could be a number of things such as more worms, food, or another illness. It sounds like this has been a persistent problem, so its a good idea to consult with your vet.
