When do Plott Hounds stop growing?

Plott Hounds reach their full height by around 12 months, but they will continue to fill out and develop muscle mass until they’re about 18 months to two years old. 

You’ll want to switch your canine BFF to adult food around their first birthday. At this point, they’ve finished most of their rapid growth, and their dietary needs shift to being less calorie-dense. It’s best to make the transition from puppy food to adult food over a week, gradually mixing the new food in with the old to prevent gastrointestinal upset.
