At what approximate age will most Scotch Collies have achieved their full adult height?

Answer

By about twelve months of age

Scotch Collies typically experience their most intense growth during their initial six months of life. However, reaching their final stature—their full height—is generally accomplished around the twelve-month mark. While they achieve height by this time, it is important to note that they continue the maturation process, 'filling out' with muscle mass and developing adult chest width, which can extend up to eighteen months or even two years.
