Dr. David Coyle has been with Pets Central since 2006. His practice is limited to internal medicine, meaning his work is almost exclusively referral and second opinion involving dealing with seriously or chronically ill cats and dogs, and investigating unusual symptoms and diseases.

He graduated with honours from the University of Queensland, Australia, in 1993, and attained Membership in the Australian College of Veterinary Scientists in the field of Small Animal Medicine in 1998, before moving to Hong Kong in 2000. He has lectured for nearly two decades on internal medicine topics in Hong Kong and China, and mentored undergraduate and postgraduate veterinary students.

Dr. Dave spends his time dealing with pets who suffer from diseases of the heart and lungs, liver and gallbladder, kidneys and urinary tract, gastrointestinal system and pancreas, adrenals and other glands, spleen, blood system and skin. He performs over 500 abdominal and 200 heart ultrasounds each year, and routinely performs minimally invasive ultrasound diagnostic procedures, saving hundreds of pets each year from diagnostic surgical procedures.

Apart from the extreme challenges of pure medicine, two other fields that he has been very passionate about for a long time are advancing pain relief in veterinary patients, and reducing the amount of vaccinations that pets undergo routinely.

He speaks moderate Cantonese, plays rugby for Kowloon Rugby Club, and is also Chair of the Tung Chung Rugby Club.
