    In puppies, the most common worm is Toxocara canis, roundworm. This worm passes through the placenta from the mother dog prior to birth or through ingestion of contaminated milk afterward. These worms live in the intestine, feeding off nutrients your puppy needs. Healthy adult dogs are able to arrest larvae growth, but puppies are susceptible to them, suffering stunted growth, vomiting, diarrhea and a pot-bellied appearance. Worming may take time to complete, but you'll see signs that the worms are leaving your puppy.

    Puppies can begin worming treatment as early as 2 weeks of age, followed by additional treatments every two weeks until 8 weeks of age. Your veterinarian performs a fecal test to identify the worms and chooses a medication designed for the specific worm infestation. While other worms may be present, roundworms are the most common in puppies.

    Your veterinarian will perform regular fecal tests to ensure worming medications potbelly is shrinking as the worms die. You may notice worms coming up in vomit or coming out with stool. A puppy who had a ferocious appetite due to the worms taking away nutrients may eat less as the worms die.
