Dog weight and body condition tracker
Log your dog's weight, see the trend on a chart and check its body condition on the 9-point scale vets use.

What it does
Add a dated weight each time you weigh your dog and the tool draws the trend, shows the change since the first entry and warns about a swing of ten percent or more. Name a breed and it compares the latest weight with the breed's typical adult range. Below the chart is the 9-point body condition scale, which is a better guide to a dog's shape than the number on the scale.
How to use it
Weigh your dog every few weeks on the same scale, at about the same time of day. For a large dog, weigh yourself holding the dog and subtract your own weight, or ask your veterinarian about weighing visits. Then look and feel: on a dog in ideal condition you can feel the ribs without pressing hard, there is a waist when you look from above, and the belly tucks up behind the ribs when you look from the side.
Where it stops being right
A breed's range describes dogs of that breed in general. A healthy dog can sit outside it, and a mixed-breed dog has no single range. The scale also cannot tell muscle from fat, which is why the body condition scale is there. A puppy is expected to gain steadily, so the ten percent warning matters most in adult and senior dogs.
Nothing here replaces an exam. If your dog is gaining or losing without a change in food or activity, or its condition score is below 4 or above 6, talk to your veterinarian.
