I'm not sure what deworming treatment you used, but if it didn't contain praziquantel, then it will not kill tapeworms if Willow has them. Tapeworms require praziquantel to kill. In addition, the life cycle of intestinal worms is around 2-3 weeks, so when a puppy does have worms, he needs to initially be dewormed every two weeks at first to kill all the worms. The first treatment kills the adults present while the second one kills the worms that had not yet hatched at the time of the first treatment. After that, he can be dewormed monthly. I would give him another deworming treatment now, one that includes praziquantel such as Drontal. Give him another dose in two weeks, and then deworm him monthly until he is six months old. After that, he should be dewormed every three months. As a side note, it is never recommended to give dogs pork. Raw pork contains parasites called trichinella spiralis larvae, which can cause the parasite infection known as trichinosis. In addition, pork can be high in fat and full of salt, both of which are not good for dogs. If you want to give him some meat with his dog food, boiled white meat chicken (no bones) or boiled low fat ground beef are better choices. Best of luck, I hope this helps!
