Pet Size

Don't know your pet's weight?

If you can't get them on the scale, try this super simple method:

  1. Weigh yourself.
  2. Weigh yourself holding your pet.
  3. Subtract the two numbers to get their weight.

Too heavy to hold? Your vet will weigh them if you ask (or may already have it on file if you call).
