Why Does My 7 Week Old Chihuahua Poop Out Worms?

These worms are intestinal parasites. Take these worms and a stool sample to your veterinarian's office. They need to identify the parasites and confirm your puppy is not infected with multiple parasites. Identifying the parasites is important so appropriate treatment can be started. Your puppy should have its first set of vaccinations as well.
