How do I know if my dog is overweight?

Feel along their ribs — you should find them fairly easily under a thin layer of fat, without pressing hard. Look for a visible waist from above and a gentle tuck from the side. If ribs are hard to feel and there is no waist, your dog is likely carrying excess weight.

Do breed weight charts actually mean anything?

They are a useful starting point but only an average, and plenty of healthy dogs sit outside their breed's typical range due to frame size and build. A hands-on body condition check tells you more about an individual dog than a chart figure alone.

How often should I check my dog's weight or condition?

Every few weeks is a reasonable habit, since it lets you catch a gradual change in direction that is easy to miss day to day. Keeping a simple note each time makes it easier to compare over months rather than relying on memory.

My dog is at the top of their breed's 'ideal' range — is that a problem?

Not necessarily. A published range is only a guide, and where your individual dog sits within or outside it matters less than how they feel on a hands-on body condition check. If you are unsure, ask your vet to assess it directly.

How much should my dog weigh?

There is no single correct weight for 'a dog' — it depends on breed, frame size and the individual animal, which is why a breed's published weight range is only a starting point rather than a target. A simple hands-on check, called body condition scoring, tells you far more about whether your dog is a healthy weight than any chart alone.

Why there's no one right weight

Breed weight ranges are averages drawn from typical dogs of that breed, and plenty of healthy individuals sit outside them simply because of frame size, build or genetics — a mixed-breed dog does not fit a breed chart at all. Treating a published range as a strict target rather than a rough guide misses individual variation that matters more than the number.

Two dogs of the same breed and similar height can have quite different healthy weights depending on how solidly or lightly built they are, which is exactly why vets use a hands-on assessment rather than relying on weight alone.

The check that matters more than a number

Body condition scoring looks at how your dog feels and looks rather than what they weigh. You should be able to feel their ribs fairly easily under a thin layer of fat without pressing hard, and without them being visibly sticking out. Looking down from above, there should be a visible waist behind the ribs, and from the side, a gentle upward tuck of the belly rather than a straight or sagging line.

A dog who fails these checks in the direction of too much padding is likely carrying excess weight regardless of what the scale says relative to a breed chart, and the same applies in reverse for a dog who feels bony with no waist tuck visible at all.

Tracking it over time

A single check tells you where your dog stands today; doing it regularly, every few weeks, tells you the direction they are heading, which is often more useful than either measurement alone. Gradual weight change is easy to miss day to day and much easier to spot when you are checking consistently.

Keeping a simple note of what you find each time — even just 'ribs easy to feel, good waist' — gives you and your vet something concrete to compare against later, rather than relying on memory of how your dog looked a few months ago.

When to get your vet to weigh in

If you are ever unsure how to assess your dog's condition, or a check leaves you uncertain either way, your vet can show you exactly what to feel for and confirm where your dog actually sits. It is also worth a check whenever you notice a real change, rather than assuming it will settle on its own.

A vet visit is also the right place to talk about how to actually shift weight safely if your dog needs to lose some, or gain it, since the right approach depends on their age, breed and any health conditions rather than a generic rule that suits every dog equally.
