Q. Is it common for puppies
to be born with worms?
A. Puppies can become infected with hookworms and roundworms while
they are still in the mother's uterus. The larvae (immature forms) of the
worms migrate through the mother's uterus and into the developing fetus.
Puppies and kittens can also be infected with roundworms and hookworms through
their mother's milk. This is why it is so important to begin a deworming
program when the puppies and kittens are 2 weeks old.
