Obesity is now the single most common nutritional disorder in UK dogs. The 2024 PDSA Animal Wellbeing (PAW) Report puts the figure at 56% of dogs and 49% of cats. The Royal Veterinary College's VetCompass database links overweight body condition to dramatically higher rates of orthopaedic disease, neoplasia and shortened lifespan. ## Health risks — and what each one costs | Condition | Typical UK lifetime cost | | --- | --- | | Osteoarthritis management | £3,000–£6,000 | | Cruciate ligament surgery (TPLO) | £2,800–£5,500 per knee | | Diabetes management (insulin + monitoring) | £1,500–£2,500/year | | Heart disease investigations | £600–£1,800 | | Anaesthetic risk premium for routine ops | £50–£150 added per procedure | Add it together and an overweight dog typically costs **£2,000–£5,000 more** in lifetime vet bills than a lean littermate. The landmark Purina 14-year Labrador study also found lean dogs lived almost **two years longer** than their overweight siblings. ## How to recognise overweight Most UK practices use the 9-point Body Condition Score (BCS). A healthy dog (BCS 4–5/9) should have: - Ribs easily felt under a thin fat layer - A visible waist when viewed from above - An abdominal "tuck" when viewed from the side ## The action plan that actually works 1. **Get an objective starting weight.** Many UK practices run free weigh-in / nurse weight clinics — book one. 2. **Calculate calories for target weight, not current weight.** Your vet can give you a kcal/day figure. 3. **Weigh food in grams.** Cups overestimate by 30–50%. 4. **Slash treats.** Replace with carrot, green beans or kibble subtracted from daily ration. 5. **Two short walks beat one long one** for weight loss and arthritis. 6. **Consider prescription weight-loss diets** (Hill's Metabolic, Royal Canin Satiety) for dogs needing >15% weight loss. 7. **Re-weigh fortnightly.** Target 1–2% body weight loss per week. ## What about ozempic-style drugs? No GLP-1 weight loss drug is currently licensed for dogs in the UK. Off-label use is not recommended; the evidence base in non-human species is poor. ## FAQs ### My dog seems hungry all the time on the diet Switch the same calorie allocation onto a high-fibre prescription weight-loss diet — satiety improves dramatically without adding calories. ### How long should weight loss take? Realistic: 4–9 months to reach ideal body condition for most dogs. * * * **About the data:** Prevalence from PDSA PAW Report 2024; lifespan data from the Purina/Nestlé Labrador Lifespan Study; UK cost data from our practice pricing database (June 2026). ## Sources & further reading - PDSA — PAW Report (animal wellbeing): https://www.pdsa.org.uk/what-we-do/pdsa-animal-wellbeing-report - RVC VetCompass — Canine obesity research: https://www.rvc.ac.uk/vetcompass - Purina Lifespan Study (Kealy et al, JAVMA): https://avmajournals.avma.org/ - WSAVA Global Nutrition Guidelines: https://wsava.org/ Browse all articles: https://vetpricecomparisonsite.co.uk/blog ## Structured data ```json [ { "@context": "https://schema.org", "@type": "WebSite", "name": "The Vet Price Comparison Site", "alternateName": "VetPrices", "url": "https://vetpricecomparisonsite.co.uk" }, { "@context": "https://schema.org", "@type": "Organization", "name": "The Vet Price Comparison Site", "alternateName": "VetPrices", "url": "https://vetpricecomparisonsite.co.uk", "logo": "https://vetpricecomparisonsite.co.uk/web-app-manifest-512x512.png" }, { "@context": "https://schema.org", "@type": "Article", "headline": "Dog Obesity UK 2026: The Hidden £3,000+ Lifetime Vet Bill (and How to Reverse It)", "description": "56% of UK dogs are overweight (PDSA PAW).
