Companion Animal Obesity: A Growing Welfare Crisis

Obesity affects a substantial proportion of companion animals and causes chronic pain, reduced quality of life, and shortened lifespan, making it one of the most prevalent and preventable welfare problems in pet animals.

Key Facts

Approximately 40-50% of dogs and cats in the UK are overweight or obese according to veterinary body condition scoring
Obesity significantly increases risk of diabetes, osteoarthritis, heart disease, and respiratory problems
Owners frequently fail to recognise overweight body condition in their pets, viewing it as normal
Caloric restriction and increased exercise are effective treatments but require sustained owner commitment
Prescription weight management diets improve compliance by providing measured daily portions with nutritional balance

Welfare Considerations

Obese animals carry excess weight that causes joint pain, makes breathing more difficult, reduces heat tolerance, and impairs the ability to groom, exercise, and perform normal behaviours. Arthritic pain in overweight animals is chronic and daily. The enjoyment of movement, play, and exploration is reduced. Life expectancy is shortened. Yet obesity is largely preventable through appropriate feeding and exercise. The welfare impact of allowing a companion animal to become and remain obese represents a significant failure of owner responsibility that veterinary practices are increasingly addressing through proactive body condition assessment.

What You Can Do

Ask your vet to body condition score your pet at every visit and act on their advice
Measure food portions accurately rather than estimating - overfeeding is the primary cause
Discuss a structured weight loss plan with your vet if your pet is overweight
Reduce treats significantly during weight loss - they are often a major caloric contribution
Increase appropriate exercise gradually alongside dietary management
