Pet obesity is a clinical disease.
Awareness is the first step.
Since 2005, the Association for Pet Obesity Prevention has provided veterinary healthcare professionals and pet owners evidence-based tools, prevalence data, and resources to support diagnosis, communication, and treatment of clinical pet obesity.

2026 Clinic Prevalence Survey
Registration is now open for the 2026 Veterinary Clinic Pet Obesity Prevalence Survey, taking place during World Pet Obesity Month in October.
U.S. veterinary teams are invited to participate by recording body condition scores for eligible dogs and cats during a designated clinic day. Participation is straightforward, and data collection can be completed in as little as one day.
International clinics are also encouraged to participate. While primary analysis will focus on U.S. trends, global participation strengthens future comparative research.
