I have a male from show lines. Just curious in general what type of growth to expect from 12 months to 18 months? He just hit a year old, I know people say they will "fill out" but just curious what that means really and what to expect in changes in him. Thank you very much!
You can ask the breeder how both sides of the pedigree mature. As long as they aren't neutered, males typically broaden in structure and many look their best at 3-4 years old.
