The Wirehaired Pointing Griffon undergoes rapid physical transformation between three and twelve months of age. During this juvenile period, puppies will grow from compact, clumsy youngsters into leggy adolescents that begin to resemble the athletic adults they will become. Most of the skeletal growth occurs during this window, with the breed typically reaching close to full height by ten to twelve months, though they will continue to fill out with muscle and mature body mass well into their second year.
Growth plates in the long bones remain open throughout much of this stage, making the juvenile Griffon particularly vulnerable to injury from excessive or high-impact exercise. Activities such as long-distance running on hard surfaces, repetitive jumping, or rough play with much larger dogs should be carefully moderated. Short, varied sessions of free play on soft ground are far more appropriate and support healthy joint development without overloading the growing skeleton.
The breed's signature wiry coat begins to change noticeably during this period. The soft, fluffy puppy coat gradually gives way to the coarser, weather-resistant outer coat that defines the breed. You may notice uneven patches as the adult coat grows in, and the texture may seem inconsistent for several months. This is entirely normal and part of the transition to the dense double coat that will protect your Griffon in the field and in harsh weather.
Regular weigh-ins and body condition assessments help you track whether your Griffon is developing at a healthy pace. Your veterinarian can provide breed-specific growth charts to compare against. Adolescent Griffons that appear overly thin or excessively heavy for their frame may need dietary adjustments to support optimal development without stressing growing bones and joints.
