My puppy had roundworms and one thing the vet said was to keep the poop picked up immediately after the dog goes because it can infect the ground. He also said that sun will kill the worms and eggs, but freezing cold doesn't. Go figure. He also said that puppies get roundworms from being passed on from the mother, so if one puppy in a litter has roundworms, the rest of the litter should also be treated. I hope your little guy is free of the worms with the one dose. I had to give Maddie medicine every two weeks for a total of 6 doses...it was liquid and she thought it was a treat because it tasted so good. |
