If you're squinting at your dog and wondering whether they've got a bit portly, you're asking a good question, and a common one. Nearly half of UK dogs are overweight, and it creeps up so gradually that most owners don't notice. The short answer: you can do a simple hands-on body condition check at home in under a minute, and if your dog doesn't have a visible waist or ribs you can feel, it's time for a chat with your vet about a healthy weight.
Extra weight isn't just about looks. It genuinely shortens dogs' lives and makes them less comfortable, so it's well worth getting on top of. Here's how I check the dogs that come through the salon, and what you can do.
The at-home body condition check
Weight on the scales only tells you so much, because the right weight for a Whippet is nothing like the right weight for a Labrador. Vets use a "body condition score," and you can do the key parts of it yourself with your hands and eyes:
- Ribs: run your hands along your dog's sides. You should be able to feel the ribs easily under a thin layer, a bit like the back of your hand. If you have to press to find them, there's too much covering
- Waist from above: look down at your standing dog. You want to see a waist tucking in behind the ribs. Straight sides or a bulge means extra weight
- Tummy from the side: the belly should tuck up towards the back legs, not hang level or sag
- Overall: you're aiming for a dog who feels trim and moves easily, not one who feels padded all over
The PDSA's guide to obesity in dogs has a clear body condition chart if you'd like a picture to compare against. Do the check with your hands, coat can hide a lot, which is one reason we sometimes spot weight changes at the salon that owners haven't clocked.
Why extra weight matters
Carrying too much weight puts real strain on a dog's body. It's linked to:
- Joint problems and arthritis, made worse by the extra load
- Diabetes
- Heart and breathing difficulties (harder still for flat-faced breeds)
- A shorter life: studies show overweight dogs tend not to live as long
- Less enjoyment: it's simply harder to run, play and get comfortable
The good news is that dogs respond quickly to sensible changes, and even modest weight loss makes a visible difference to how they move and feel.
Vet note: Before starting any weight-loss plan, check in with your vet. Sudden or unexplained weight gain can occasionally point to a health condition like an underactive thyroid, and your vet can rule that out and set a safe target weight and pace for your particular dog.
Healthy-weight tips that work
Weight loss for dogs comes down to slightly less in, slightly more out, done steadily. Practical steps:
- Measure meals with proper scales rather than eyeballing a scoop, and feed to your dog's target weight, not their current one
- Count the treats. They add up fast. Swap high-calorie treats for small pieces of their kibble allowance, or low-calorie options like carrot or green beans
- Cut the extras: table scraps and leftovers are usually where hidden calories hide
- Build activity gently: a little more walking, some sniffy exploring and play, increased gradually
- Ask about a weight-loss diet. Vet practices often run free nurse-led weight clinics to weigh, advise and cheer you on
Go slow and steady. Crash diets aren't safe for dogs, and a gradual approach is far more likely to stick.
When to talk to your vet
Book a chat with your vet if:
- Your body condition check suggests your dog is overweight
- The weight went on suddenly or without an obvious reason
- Your dog is also drinking more, low in energy, losing coat quality or has a pot-bellied look
- You want a safe target weight and a plan tailored to your dog's age, breed and health
Your vet or vet nurse can weigh your dog properly, rule out underlying conditions and give you a realistic plan. For more background, the PDSA Pet Health Hub has plenty of vet-written advice on keeping dogs at a healthy weight.
Frequently asked questions
How can I tell if my dog is overweight?
Feel for the ribs (they should be easy to find under a thin covering), look for a waist from above, and check the belly tucks up from the side. If ribs are hard to feel and there's no waist, your dog is likely carrying too much weight, and your vet can confirm with a body condition score.
What health problems does being overweight cause in dogs?
Extra weight is linked to arthritis and joint pain, diabetes, heart and breathing problems, and a shorter lifespan. It also simply makes everyday movement and play less comfortable.
How do I help my overweight dog lose weight safely?
Measure meals to their target weight, cut back on treats and table scraps, and build up gentle exercise gradually. Always check with your vet first, and consider a free weight clinic at your vet practice for support and regular weigh-ins.
Could sudden weight gain be a medical problem?
It can be. Conditions like an underactive thyroid can cause weight gain, so if your dog has put on weight suddenly or without a clear reason, it's worth a vet check before you change their diet.
