The Pennsylvania SPCA is urging dogs owners to have their pets vaccinated against Canine Parvovirus (CPV) after an early uptick in the cases of the often-fatal disease.
"Parvo is one of the most deadly viral illnesses in our canine population," said Dr. Lisa Germanis, a staff veterinarian on at the PSPCA, said in a statement. "In the past two weeks, we've seen more than 20 cases of parvo in our veterinary clinic. Typically we don't begin to see this many cases until later in the spring and summer."
