How can I tell if my dog is overweight?

Published October 24, 2026

The short answer

The most reliable home test is your hands, not the scales. Run your palms along your dog's ribcage with light pressure: you should be able to feel the ribs easily under a thin layer of fat, the way you can feel the bones on the back of your hand — if you have to press to find them, there is too much coverage. With KinsLe's Pet Passport, each weigh-in and body-condition note joins your dog's vaccination record and vet history in one portable packet, so progress is easy to show at every check.

A woman kneels beside a standing yellow Labrador in profile, placing her hands around its ribs and waist to feel its body shape.

Scales alone will not tell you whether your dog is carrying too much weight — your hands will. Rest your palms flat against the ribcage and move them slowly backward with gentle pressure. Ribs that surface easily beneath a slim fat layer are what you want to feel, much like the bones across the back of your own hand; needing to push in to locate them signals excess coverage. From above, look for a visible waist behind the ribs; from the side, the belly should tuck upward behind the ribcage rather than sagging level or hanging down.

Using Body Condition Honestly

Vets score body condition on a 9-point scale, with 4–5 ideal; you can use the same feel test monthly and photograph your dog from above and the side to make slow change obvious. Weight gain creeps in through measured-food drift (heaped scoops, uncounted treats and chews, tidbits from children's plates) and reduced exercise in bad weather or as dogs age. If your dog is carrying extra, the fix is gradual: accurate measured portions of a complete food, treats swapped partly for vegetables like carrot or green beans, and exercise built up gently — crash diets are never appropriate for dogs.

Working With Your Vet

Weight calls for the same honesty at the surgery. Tell the vet what actually goes into the bowl each day — measured food, chews, treats, and scraps included — and when you first noticed the waist disappearing, then let the veterinarian weigh your dog, score body condition hands-on, and judge whether the gain is feeding, age, or something medical underneath. General guidance can show you how to run the rib test at home, but it cannot set a target weight or rule out causes like an underactive thyroid; that judgement belongs to an examination. Photographs taken from above and from the side, a month apart, give the vet change they can see rather than a guess from memory.

Ask your vet to confirm your dog's ideal weight at the next visit — they will weigh, score condition, and set a target. Book sooner if weight has changed quickly in either direction without an obvious cause, because unexplained change can be a health sign as well as a feeding issue.

Keep the numbers where you can see them drift. Weigh your dog monthly — at the vet's scales or a pet shop's — and write the figure down beside portion sizes, daily treats and chews, and minutes of exercise. A two-pound creep across three quiet months is easy to miss on a dog you see every day and impossible to argue with on paper. Recheck the picture whenever life shifts the equation: neutering, a slower senior routine, winter weather cutting walks short, or a new household member whose treat habits differ from yours.

Store those weigh-ins with vaccination dates and visit summaries, and each appointment starts from evidence instead of recollection. Pet Passport in KinsLe gathers a dog's weight record, vet history, and feeding notes into a single portable packet, ready for appointments, travel, boarding stays, and handoffs to sitters.
