HLES_DogDemographics

About the Dog Demographics Survey

The Dog Demographics Survey contains owner-reported information about the dog at the time of enrollment, including age, weight, breed status, reproductive history, and other information that may change over time as the dog ages. Our team uses this information to classify dogs into life stages, based on size. Genetic breed status, which may or may not agree with owner-reported breed, is available for subsets of the overall study population. Refer to the Dog Overview dataset for information about genetic data availability.
