How do I know when to worm my puppy?

As a breeder, I automatically worm all my pups at 2, 4, 6 and 8 weeks. I purchase a liquid wormer from my vet so I can be sure they’re parasite free. After this, you might want to take a stool sample with you when you take your pup to the vet for his vaccines so it can be examined for worms. A pup with untreated worms can go down hill quite quickly, so it’s always best to catch them early. I worm my adult dogs once a month when I give them their heart worm preventative.
