What age does chihuahua stop growing? Chihuahuas typically reach their full size between 6 and 8 months of age. However, some Chihuahuas may continue to grow until they are 12 months old. The growth rate of a Chihuahua will vary depending on the individual dog’s genetics, diet, and overall health, so it is important to consult with a veterinarian to determine when your Chihuahua is likely to stop growing.
