What age does a Wire Fox Terrier stop growing?

Wire Fox Terriers typically stop growing in height and length by the time they are about 12 to 18 months old. After they reach this milestone, Wire Fox Terriers will continue to fill out and gain muscle mass until they are around two years old. The size, height, and weight of individual dogs may vary. Proper nutrition, exercise, and consistent vet care can support healthy growth and development.
