Depending on their breed and size, dogs do not grow at different ages. Small animals usually stop growing at 12 months of age, while larger animals may continue to grow for 18 to 24 months. Some of the larger ones, like Great Danes, may regrow after two or three years.
It’s important to remember that growth is about more than size. Although bones grow steadily as dogs age, they can gain weight and build muscle throughout their lives if they don’t exercise and eat properly. In order to stay healthy and develop muscle mass, your dog needs a healthy diet as well as regular physical activity.
When do dogs not grow?
Yes, as I said before, the size and breed of your puppy determines when growth stops. Here are some general rules:
Chihuahuas, Dachshunds and Pomeranians are examples of small animals that generally do not grow after 12 months. By then they will have reached their full height and weight.
Growth in medium breeds such as beagles, cocker spaniels and bulldogs generally stops between 12 and 16 months of age. Large breeds such as German Shepherds, Boxers and Labrador Retrievers can grow to be 18 to 24 months old.
Larger animals may take longer to reach full size. Some Great Danes, Mastiffs and Saint Bernards do not stop shedding until they are 2 or 3 years old. Again, this is just a recommendation and some dogs should not grow at this age. It’s best to consult your veterinarian to get a better idea of when your dog should stop growing.
