Fecal samples from puppies with gastroenteritis less than 7 months old were examined for canine parvovirus infection (CPV-2) by hemagglutination (HA) and subsequent hemagglutination-inhibition (HI) tests. Forty of the 79 samples collected from April 1995 to June 1997 were found to be positive. About 70 percent of these samples were from 2 to 4 months old puppies, age in which they are at increased risk of developing CPV-2 infection, despite of vaccination. No seasonal distribution of canine parvovirus cases was found and it was supported by the results of a retrospective study realized at PolVet-UFF, which showed that gastroenteritis cases occurred throughout the year, for a six-year period (1991-97) in Niterói, Rio de Janeiro
