Infectious gastroenteritis are one of the main causes of dog hospitalization, etiological agents identification is a challenge for veterinarians, given that gastroenteritis etiology is caused by diverse pathogenic agents, mainly co-infections among virus or bacteria. [1] [2] [3] Canine parvovirus (CPV-2) is a member of the Parvoviridae family, belonging to the Protoparvovirus genus and Carnivore Protoparvovirus type 1 species. Diverse reports indicate that is the most diagnosed viral agent in gastroenteritis. 4, 5 Over the past years, CPV-2 has developed new antigenic variants.
