Worming puppies As mentioned, the pups may have been infected in the uterus (before birth) and will soon ingest worms in the mother's milk and from the mother's faeces if the mother is carrying an infestation also.
Do puppies get worms from their mother's milk?
Almost all puppies will be infected with roundworms, either before birth by in utero infection or after birth via their mother's milk, so even those that appear healthy will usually have some worms inside them.
Can puppies transfer worms?
The short answer is yes, many worms infesting dogs are zoonotic, meaning they can be transmitted from animals to humans.
