Harrier puppy growth: milestones and weight estimates
How fast a Harrier puppy grows, illustrative weight estimates and the limits of predicting adult size.
Harrier puppies grow steadily, reaching adult height by about 12 months and filling out with muscle until 15 to 18 months. They are sturdy, curious puppies who follow their noses everywhere, so recall practice with a long line and crate training should both start in the first weeks at home.
Protect growing joints by avoiding long runs or forced exercise until growth is complete, typically between 12 and 15 months; free play on soft ground is ideal. Watch for limping or stiffness after play, and check with a vet if these signs last more than a day or two.
