I'm so sad, my puppy has roundworms. We have started him on the dewormer today and hope to alleviate that problem. I know that we are supposed to do it about 3 or 4 times with 2 week intervals but does any one know how soon they will start to expel from my pup?

they should start within hours to expel. most all puppies & kittens have them. did you get the medication from the vet?

Hope your puppy will get rid of those worms. Let the vet check him after a week or two to ensure every single one was gone.
