Obesity affects over half of companion dogs and cats in many countries, causing chronic pain, reduced mobility, and shortened lifespan. Addressing pet obesity is one of the most impactful welfare improvements owners can make.
Pet obesity is one of the most widespread and preventable sources of chronic suffering in companion animals, yet it is frequently overlooked because overweight pets look comfortable and content. The reality is that obese animals carry excess weight on skeletal systems not designed for it, causing joint stress, pain with movement, and reduced ability to engage in the behaviors that provide quality of life. Obese cats are prone to diabetes that requires daily management and can cause ketoacidosis. Obese dogs develop arthritis earlier and more severely. The normalization of overweight pets in popular culture — where round, heavy animals are often considered cute rather than unhealthy — is a significant barrier to owner recognition and action. Veterinary engagement and owner education about healthy body condition scoring are the most effective levers for change.
