You can get a good sense of whether your dog is a healthy weight at home using three quick checks: you should be able to feel their ribs easily without pressing hard, see a visible waist when you look down from above, and see a tummy that tucks up when viewed from the side. If ribs are hard to find and the waist has disappeared, your dog is likely carrying extra weight.
Because ideal weight varies enormously between breeds, this “body condition” approach is more useful than any single number on a scale.
The Three At-Home Checks
- The rib checkRun your hands along your dog’s sides. You should feel the ribs under a thin layer of fat, a bit like feeling the back of your hand. If you have to press to find them, that points to overweight; if they’re sharply visible without touching, that can point to underweight.
- The waist checkLook down at your dog from above. A healthy dog has a visible waist that narrows behind the ribs. A straight or bulging outline suggests excess weight.
- The profile checkLook from the side. The belly should tuck up from the chest toward the back legs rather than hanging level or sagging downward.
Why Weight Matters
Even a little extra weight adds up over a dog’s life. The consequences are real:
- Joint strain and arthritisExtra weight puts constant pressure on joints and significantly worsens arthritis — the leading cause of chronic pain in older dogs.
- Heart and breathing problemsExcess fat puts strain on the heart and lungs, reducing stamina and increasing the risk of serious conditions.
- Shortened lifespanStudies consistently show that dogs kept at a lean, healthy weight live significantly longer than overweight counterparts.
Underweight dogs have their own issues too — possible parasites, illness, or simply not getting enough food. Both extremes deserve attention.
Track the Trend, Not Just the Number
A single weigh-in tells you little; the direction over weeks and months tells you a lot. Weigh your dog regularly under the same conditions (same scale, ideally same time of day) and watch the curve.
- Small dogsCan be weighed by holding them on a bathroom scale and subtracting your own weight.
- Larger dogsEasiest to weigh at the vet’s, though many pet shops have walk-on scales too.
Logging each measurement makes trends obvious. In the Yuki app you can record your dog’s weight over time and see it as a clear chart — so you can spot a slow creep upward before it becomes a problem and share the history with your vet at the next visit.
What to Do If Your Dog Is Overweight
Start with your vet — they can rule out medical causes like thyroid issues, recommend how much to reduce portions, and advise on a safe weight-loss pace. Generally: reduce food slightly, cut treats, and increase activity gradually. Crash diets are as bad for dogs as they are for people.
When to See a Vet
If your dog is clearly over- or underweight, or if weight changes suddenly without a change in food or exercise, book a check-up. Sudden loss or gain can signal a health issue that needs attention — don’t wait to see if it resolves on its own.
