Morris Animal Foundation Data Commons is a free resource for the scientific research community. Data Commons provides open access to most of the data collected by the Golden Retriever Lifetime Study, covering 11 key subject areas: activity, behavior, dental, disease diagnoses, diet, environment, grooming, geographical locations, medications, physical exams and reproduction. Data is collected annually on each of the approximately 3,000 golden retrievers in the cohort, sourced from both owners and veterinarians.
