At what age does bone growth stop? Not length but when you'd make a comment that a dog has good bone. I guess it would be circumference?

I'd be interested to know as well 😎

I feel it depends on the lines. Certain lines you'll see bone growth for longer than from other lines.

I have a girl who grew more bone until close to 2.5 years in age. I never saw that prior but heard 1 of the lines fairly heavy within her pedigree grows bone for longer than most other lines. I feel her first litter also helped at a bit over age 2, once all of her clearance were back and she came into season.

I'm pleased with how she turned out yet worried between age 1 and 2 unneccesarily.

I don't know if there is an average age when bone growth subsides. I've seen different ages with different Labs, my own and others.
