I dont know but i bleached everything and he is dewormed now and get another dose next time we go to the vet. Now you making me scared are they really that bad? I defiantly stay away from craigslist next time lessen learned.
Hookworms CAN be very bad...especially for young puppies. In extreme cases they can cause anemia and even death. BUT please don't let that scare you. Your puppy doesn't seem to have a case that severe as long as he's still acting normally. The wormer will take care of them and he should be just fine.
