At what age do dogs stop growing? - briefly
Dogs typically stop growing in height between 6 and 18 months of age, depending on their breed and size. After this period, they may continue to fill out and develop muscle mass until they reach full maturity, which can take up to two years for larger breeds.
At what age do dogs stop growing? - in detail
Determining when a dog stops growing is influenced by several factors, primarily breed and size. On average, smaller breeds tend to reach their full adult size and weight more quickly than larger breeds.
For small to medium-sized breeds, such as Chihuahuas, Dachshunds, and Yorkshire Terriers, growth typically plateaus between 6 to 8 months of age. By this time, they have usually reached their full adult size and weight. However, it's important to note that they may continue to fill out and develop muscle mass until they are around a year old.
In contrast, larger breeds like Golden Retrievers, Labradors, and German Shepherds take longer to reach maturity. These dogs often continue growing until they are 12 to 18 months old, sometimes even up to 24 months for giant breeds such as Great Danes and Saint Bernards. Even after reaching their full height, these larger breeds may still be filling out and developing muscle mass well into their second year.
Additionally, spaying or neutering a dog can affect its growth rate. In some cases, this procedure can cause the growth plates to close prematurely, leading to slightly shorter stature than if the dog had not been spayed or neutered. However, the impact varies and is not significant in most cases.
Regular veterinary check-ups are essential for monitoring a dog's growth and ensuring they are developing at a healthy rate. If there are any concerns about a dog's growth, it's always best to consult with a veterinarian who can provide personalized advice based on the specific breed, size, and health history of the dog.
