How Often Should I Weigh My Dog?
Weigh a healthy adult dog about once a month, and a dog on a weight-loss plan every one to two weeks. Puppies need weekly weighing while growing. Frequent weighing catches a trend early, before you can see or feel it, and lets you adjust the portion before a few ounces become several pounds.
How often should I weigh my dog?
Match the frequency to the situation:
- Healthy adult at ideal weight: about once a month. Enough to catch slow drift without becoming a chore.
- Dog on a weight-loss plan: every 1–2 weeks. You need this cadence to see whether you're hitting the 1–2% per week target and to adjust before the plan drifts off course.
- Growing puppy: weekly, because they change fast and feeding should track a healthy growth curve.
- Senior or dog with a health condition: at least monthly, more often if your vet advises.
Pair every weigh-in with a quick hands-on body condition check. WSAVA recommends assessing body condition at every visit precisely because the scale and the hands answer different questions (WSAVA Global Nutrition Guidelines).
Why does weighing frequency matter?
Because weight problems are invisible until they aren't. A dog that gains a half-pound a month looks identical day to day, but that's six pounds a year — a big deal on a 40-pound frame. Regular weighing turns an invisible trend into a number you can act on early.
It also keeps a diet honest. In one weight-loss program, 64.4% of dogs failed to reach the recommended weekly loss rate, and the plans that worked were the ones where owners tracked and adjusted (canine weight-loss review, PMC). Weighing every week or two is how you notice a stall in time to fix it.
| Dog's situation | Weigh how often | What you're watching for |
|---|---|---|
| Healthy adult | Monthly | Slow drift up or down |
| Weight-loss plan | Every 1–2 weeks | 1–2% per week loss; stalls |
| Puppy | Weekly | Steady, not-too-fast growth |
| Senior / medical | Monthly or as advised | Unexpected loss or gain |
How should I weigh my dog at home?
For small dogs, a baby or kitchen scale is accurate and repeatable — the same trick vets suggest for cats, using a baby scale to catch small changes (Cornell Feline Health Center). For larger dogs, weigh yourself, then weigh yourself holding the dog, and subtract. Use the same scale each time — consistency matters more than absolute accuracy for tracking a trend. Log the number so you can see the line, not just the latest point.
Turn the number into action
The scale is only useful if it feeds a decision. Check whether the current weight is actually right with our body condition check, set or update a calorie target with the dog calorie calculator, and if your dog is dieting, pace it with how much weight a dog should lose per week.

Frequently asked questions
How do I weigh a big dog at home?
Weigh yourself, then weigh yourself holding the dog, and subtract. A bathroom scale works for small changes, though a vet or pet-store scale is more precise for large dogs.
Does weighing replace the body condition check?
No. The scale tracks change; the hands-on body condition check tells you whether the current weight is right. Use both together.
