Just curious if anyone might have an educated guess! :educated: She's 13 months old and currently weighs about 58. She's 15 inches around the neck, 27 chest and 18 tummy. Her momma weighed about 70 and her daddy about 80.
I have to disagree a bit. It depends on the lines. My boy gained about 10-15 pounds from 15mo - 4 years of age when he was mature.
My Lily gained about 10lbs from that age until 3. She also gained some girth from last year to this year. By about 2 inches.
Rhumba is 17 months and I have not had her on the scale in a while but at 13 she was about 63lbs. By the time she is 3 I suspect she will be in the 70's. Lily, even though she does not look like it, is about 75lbs.
Lily also gained about an inch in height between 13-16 months.
So it all really depends. Sometimes littermates way outgrow the others and even their parents. Other times you get ones who are much smaller.
I do not consider a Lab done growing until 3-4.
For measuring, we usually measure HEIGHT. From the withers (shoulder blades) to the floor/feet.
My experience is most dogs by 13 months are usually as tall as they will be give an inch or so. Mine always fill out 10-15 pounds in that last year or so though. By the time the dog is 2 or 3, that's what you will have as an adult dog.
