Roundworms can complete their life cycle in immature dogs, but as the pup's immune system matures (usually by 6 months of age), the larval stages of the roundworm will become arrested and will encyst (become enclosed in a cyst) in the pup's muscles. They can remain encysted in the dog's tissues for months or years.
Can worms just crawl out of dogs?
A tapeworm can grow from 4 to 8 inches long. Chances are you won't see the adult worm. As it grows, though, some of its segments fall off and pass through your dog's poop. You may see these tiny parts crawling near your dog's backside or on their bedding.

How long after deworming will my dog pass worms?
