The incidence of gastroenteritis diagnosis among sick dogs presented to the Onderstepoort Veterinary Academic Hospital correlated with meteorological data.

The number of sick dogs diagnosed with and without gastroenteritis presented to the Onderstepoort Veterinary Academic Hospital situated north of Pretoria is reported from counts extracted from the records of the Outpatients clinic for 6 years, 1988 to 1993. The average percentage of sick dogs diagnosed with gastroenteritis was 11.51% and the average percentage of sick dogs that were admitted to the parvovirus isolation hospital ward was 2.8%. A strong correlation exists between the number of dogs admitted to the parvovirus ward and average monthly wind speed and inverse humidity values.
