It is possible for even an indoor puppy to get worms passed through their mother's milk, according to WebMD. These parasites weaken the puppy's body and can even kill, which is why it is important to begin a deworming regimen early.
Take the puppies to the vet at about 2 weeks of age for a first check up. Take along some stool samples, if the vet requests it, for the vet to check under a microscope. These samples will show whether the puppies are already infected with parasites or not.
The vet will likely recommend deworming as a preventative, and may even give the first dose to the puppy. These treatments can be oral or an injection and are usually a broad spectrum anti-parasitic, according to WebMD.
Doctors Foster and Smith state that puppies usually receive doses of dewormer again at 4, 6 and 8 weeks of age, followed by a once-monthly dose for a lifetime of protection. WebMD states that heart worm treatments are given by the vet in three doses over 2 months time.
