"Veterinary clinical studies conducted to investigate novel therapies or to collect samples or information to gain further understanding of a disease provide the best scientific evidence to guide the clinical care of animals, and oftentimes, people too. ... Veterinarians and animal owners may search the site to find studies that might be relevant to their patient or pet, either for a particular condition or even to provide health data or a sample from a normal animal. Animal owners interested in participating in such studies are encouraged to discuss their eligibility for any relevant study with their veterinarian."
