ROANOKE, Va. (WFXR) — A Roanoke veterinarian says you may not know just how many shots your pooch needs in order to be vaccinated against serious illnesses.

Parvovirus is a highly contagious disease in dogs — but it’s preventable.

Dr. Maureen Roberts, veterinarian and CEO of Emergency Veterinary Services of Roanoke, says you need to have your puppy vaccinated every two weeks when they’re between six and 14 weeks old.

“The easiest thing that we can do is to prevent it, and it’s easily preventable. Our vaccines are highly effective against this disease,” said Roberts.

She adds that a few things to watch out for in puppies are vomiting and diarrhea.

If your dog is showing signs of parvo, they need to be quarantined from other puppies immediately.
