my pups are now 8 weeks and doing great. At about 6 weeks I dewormed them out, because I was seeing worms in their stools, loose stools, ROUND stomachs and not as active. I used nemex-2 it it got rid of their worms, they where active, stools where normal and I continue to worm them about every 4-5 days until they are about 10 weeks. BUT when done feeding there stomachs continue to get round, I thought it was just puppy potbelly, but any advise would help
