How Much Should My Dog Weigh? UK Breed Weight Chart and Tracking Guide

According to the PDSA PAW Mini Report 2025, veterinary professionals estimate that 46% of UK dogs are overweight or obese - and 82% of owners are unaware of their dog's body condition score, meaning most overweight dogs are not recognised as such by the people who feed and care for them. It's one of the most common and preventable health problems in pet dogs - and one of the hardest for owners to recognise, because the change happens so gradually that it becomes the new normal.

This guide gives you the numbers, and more importantly, the tools to assess your dog's weight without needing a vet visit.

Why Weight Matters

Extra weight in dogs isn't just cosmetic. It's associated with:

• Shortened lifespan (studies suggest up to 2 years shorter for obese dogs)
• Higher risk of joint problems, particularly hip and elbow dysplasia
• Increased risk of diabetes
• Higher anaesthetic risk
• Heart and respiratory problems
• Reduced exercise tolerance and quality of life

Dogs respond well to controlled weight loss when it's managed properly.

Weight Ranges for the UK's Most Popular Breeds

These are typical healthy adult weight ranges. Individual variation is normal - some dogs will be healthily at the lighter or heavier end.

| Breed | Typical Weight Range | | ------------------ | ---------------------------------------- | | Labrador Retriever | 25–36 kg | | French Bulldog | 8–14 kg | | Cocker Spaniel | 12–16 kg | | Golden Retriever | 25–34 kg | | German Shepherd | 22–40 kg | | Border Collie | 14–22 kg | | Springer Spaniel | 18–25 kg | | Beagle | 9–11 kg (miniature), 10–13 kg (standard) | | Dachshund | 3–5 kg (miniature), 7–15 kg (standard) | | Cockapoo | 5–11 kg (varies by parent size) |

Note that weight range alone isn't the whole picture. A 30kg Labrador may be perfect or may need to lose weight - body condition matters more than the number.

The Body Condition Score: What It Actually Tells You

Vets use a Body Condition Score (BCS) on a 1–9 scale to assess weight:

• 1–3: Underweight - ribs, spine, and hip bones visible from a distance
• 4–5: Ideal - ribs felt easily, with slight fat cover; waist visible from above and side
• 6–7: Overweight - ribs harder to feel; waist less defined
• 8–9: Obese - ribs very difficult to feel; little waist definition; fat deposits visible

How to assess at home

The rib test: Place your hands on your dog's sides with thumbs on the spine and fingers spread over the ribcage. You should be able to feel ribs easily with light pressure - similar to pressing the back of your hand. If you have to press hard to find them, your dog is likely overweight.

The waist test: Look at your dog from above. There should be a visible narrowing behind the ribs. From the side, there should be a slight tuck up from the chest to the abdomen.

Weight Tracking: Why the Trend Matters

A single weight measurement tells you very little. A trend tells you whether things are moving in the right direction or not. The PDSA's 2024 'Big Weigh In' campaign found that 45% of all pets weighed during February and March had a body condition score of six or above, indicating they were overweight or obese - a figure consistent with the broader veterinary estimate of 46% of UK dogs being above a healthy weight.

Monthly weigh-ins are sufficient for most adult dogs. If your dog is on a weight loss programme, your vet may recommend fortnightly. If you're tracking in Pup Notes, you'll build up a weight graph automatically as you log - making it easy to spot gradual drift before it becomes a significant problem.

When to Talk to Your Vet

See our monitoring guides for the conditions most commonly linked to weight change: obesity and weight management, diabetes, hypothyroidism, and cancer.

• If your dog has gained or lost more than 10% of their body weight without an obvious dietary cause
• If weight loss is accompanied by increased appetite (possible metabolic condition)
• If you're unsure what your dog's ideal weight should be
• If you want to put your dog on a weight loss plan - doing it unsupervised carries risks

Vets can perform a formal body condition assessment and recommend a specific caloric target, which is far more useful than generic advice about feeding less.

Frequently Asked Questions

My dog looks fine but the scales say overweight - who's right? The body condition score is more reliable than breed averages, but combined with regular weight monitoring it's the full picture. If your vet says your dog needs to lose weight, take it seriously - owners often underestimate their dog's weight because the change is gradual.

How do I weigh my dog at home? Small dogs: step on the scales holding your dog, then weigh yourself alone and subtract. Medium/large dogs: most vets will let you pop in for a weigh-in at no charge.

Is it dangerous for dogs to lose weight quickly? Yes. A controlled reduction in calories - typically 10–20% below maintenance - is the recommended approach. Crash dieting in dogs can cause serious health problems.

Which breeds are most prone to obesity? Labradors, Cocker Spaniels, Beagles, Golden Retrievers, and Pugs are particularly prone to obesity. Labradors often carry a specific gene variant (POMC) that affects their sense of satiety - they'll eat past the point of fullness.
