Yes, there are multiple, evolving strains of canine parvovirus (CPV-2), with CPV-2a, CPV-2b, and the newer, highly virulent CPV-2c being the primary variants causing disease today. While they all produce similar, severe gastrointestinal symptoms, these strains can differ in severity, with 2c being particularly aggressive.

How many types of parvo are there?

There are two types of canine parvovirus, canine minute virus (CPV-1) and CPV-2. CPV-2 causes the most serious disease and affects domesticated dogs and wild canids, including foxes, wolves and skunks (Holmes et al., 2013).

Are there different strains of parvo in dogs?

The most significant canine parvovirus strains are CPV-2, CPV-2a, CPV-2b, and CPV-2c. These strains all cause the same disease, and vaccines protect against all strains. CPV-2b and CPV-2c are associated with the most severe disease, and are the main strains found in North America.
