World Pet Obesity Month - October

Registration is now open for the 2026 Veterinary Clinic Pet Obesity Prevalence Survey, taking place during World Pet Obesity Month in October.

We are inviting U.S. veterinary teams to register now and plan to body condition score 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 sign up. While our primary analysis will focus on U.S. trends, global participation strengthens future comparative research.

Every score counts.

Guidelines for Pet Obesity Communication

How we talk about obesity matters. Clear, accurate, and compassionate language improves adherence and reduces stigma.

These guidelines were developed to support veterinary teams, media professionals, and pet health advocates in discussing obesity as a chronic, treatable disease. The resource includes recommended terminology, framing strategies, and practical examples for clinical settings.

Whether you are speaking with clients, giving interviews, or developing educational materials, these guidelines provide a consistent framework grounded in current research.

2024 Pet Obesity and Nutrition Survey

More owners recognize unhealthy weight in pets, but awareness of Body Condition Score (BCS) remains low. Only 45% of dog owners and 40% of cat owners report familiarity with BCS, and fewer than 30% recall receiving a score from their veterinarian.

These findings highlight a gap between clinical assessment and client understanding. Increasing consistent use of BCS in practice is one of the simplest ways to improve communication and early intervention.

The 2024 report provides national data on owner awareness, feeding habits, and weight perceptions to support evidence-based conversations in the exam room.
