Dogs are dewormed externally. If the worms are still alive, they may escape to people. If the worms are dead, they will not escape to humans. Therefore, you need to pay more attention if there are live parasites on your dog. If there are parasites, it is best not to have close contact with the dog, and at the same time, deworm the dog as soon as possible. If there are many parasites, you can directly take a medicated bath, which will have a faster effect.
