When do Wirehaired Pointing Griffons stop growing?

Wirehaired Pointing Griffons stop growing in height between nine and 12 months of age, depending largely on whether they are male or female, as this breed can feature notable size differences between the sexes. After they reach their full height, they will gradually gain muscle mass until they are 16 to 24 months old. 

As Wirehaired Pointing Griffons mature, their coat develops from a softer puppy coat to the dense, wiry texture characteristic of the breed. This coat change is completed by the time they are around 18 months old.
