Ninety-two stray dogs, ranging in ages from 6 weeks to 9 years were studied to determine their serological status to canine parvovirus (CPV-2) and canine distemper virus (CDV). Using a Dot Blot ELISA, 80.4% of dogs were seropositive to CPV-2 with 78.3% having protective antibody titers (PATs), while 64.1% of dogs were seropositive for CDV with only 39.1% having  PATs (χ2=19.7;  p<0.001). No significant differences in PATs to both CPV-2 and CDV were observed between male and females. In 23 puppies less than 6 months of age, 52.2% had PATs to CPV-2 compared to 8.7% which had PATs to CDV. In dogs over 1 year of age, 96.8% had  PATs to CPV-2 as compared to 40% of dogs less than 1 year of age (χ2=38.3; p<0.001). Similarly, the majority of dogs with PATs to CDV (54.8%) were 1 year of age and older compared to 6.7% of dogs with PATs to CDV that were less than 1 year old (χ2=19.7; p<0.001). More than 90% of puppies in this study had inadequate (non-protective) CDV antibody titers. Dog owners across Trinidad should therefore be encouraged to vaccinate their animals on a regular basis since most owned dogs are not confined to their properties and contact with stray dogs is inevitable. Each year there is a growing number of stray dogs, as owners dump unwanted puppies in public places. These results emphasize the need for improved legislation, more animal shelters and responsible dog ownership in Trinidad.
