The number on the scale might not be the best indicator of your dog's healthy size.

Wouldn't it be easy if you could just weigh your dog and know instantly that she was just the right weight, just the right size, and perfectly healthy? Bad news: It doesn't work that way.

If you own a purebred dog, the American Kennel Club does offer an extensive weight chart for male and female adult dogs by breed. You can use general numbers to estimate how big a new purebred puppy might get. But if you've got one of the country's millions of mixed breed dogs, dog weight calculators and charts are only so helpful.

"It's really difficult to know a healthy weight for a dog with just the scale," says Lori Prantil, MPS, DVM, who counsels pet owners on nutrition at VCA South Shore Weymouth. "There are so many different breeds, and so many mixed breeds."

Veterinarians don't judge a dog's healthy weight with one number. They also use body condition scoring and muscle condition scoring to figure out whether your beloved pooch is carrying too little or too much fat on her body, or whether her muscles are starting to lose mass and definition.

Assessing your dog's healthy weight starts with regular visits to the veterinarian (Prantil recommends twice a year). Your careful attention over time to how your dog's weight or body condition changes is also crucial.
