That should be fine - the only other thing a vet is likely to suggest is using Stronghold on him every month, to kill fleas (which are worm hosts) and existing roundworms. If he had a large worm burden when you got him (it sounds as though the farmer might not have been telling the truth :( - it's unusual to have worms passed with Drontal) then the course you've given him
should have sorted them out. If you're at all concerned then a vet visit wouldn't go amiss. By the way, is this the pup who was 12 weeks old back in November when you got her and posted about her, or another one? It sounds very like the one with worms that your friend got - did your friend pass him on to you? You must have your work cut out with
two puppies!
