How heavy is a nine week old Labrador Retriever?

Answer 1

Because Labs are bred differently, it is hard to say what the actual target weight should be in pounds. Instead, make sure that the puppy is otherwise lively and healthy, with a shiny coat. You should be able to see a distinct waist below the rib cage; if you cannot, the dog is probably overweight. You should also be able to feel, but not see, ribs, with your hands. If you cannot feel ribs, the dog is also too heavy. If you can see ribs, the dog way too thin.

Answer 2

A full grown Labrador weighs 55 to 80 pounds (males average 72 pounds, females average 62 pounds).
