Companion Animal Obesity and Welfare Consequences

Obesity affects around 40-50% of UK companion dogs and cats, causing joint pain, breathing difficulties, and shortened lifespan - a major welfare problem driven by owner behaviour.

Key Facts

Around 40-51% of UK dogs and 39-52% of cats are estimated to be overweight or obese
Obese dogs develop joint pain, breathing difficulties, and are at higher surgical risk
Body condition scoring is a simple tool that allows owners to assess pet weight objectively
Labrador retrievers have a genetic mutation increasing food motivation and obesity risk
Cats that are obese are at significantly higher risk of diabetes and hepatic lipidosis
Veterinary advice on pet nutrition is often sought too late - annual BCS checks are recommended

Welfare Considerations

Pet obesity is one of the most widespread preventable welfare problems in the UK. Overweight animals experience chronic joint pain that limits movement, reducing quality of life. Obese cats with hepatic lipidosis face a life-threatening condition requiring intensive treatment. The welfare harm is prolonged - years of impaired mobility and increased disease risk. Owner perception is a major barrier: studies show owners consistently underestimate their pet's weight. Framing obesity as a welfare issue rather than just a cosmetic one, and training vets to discuss it without shaming owners, are key behaviour change strategies.

What You Can Do

Ask your vet to body condition score your dog or cat at every visit
Measure pet food rather than pouring it to avoid inadvertent overfeeding
Resist giving treats in excess - treats should be under 10% of daily calorie intake
Increase play-based exercise for both dogs and cats to support healthy weight
Seek veterinary advice early if your pet starts gaining weight - intervention is easier when earlier
