Many dog breeds are considered to be fully grown by the time they reach 12 months of age, but this is not true for all breeds. The age at which a dog is considered fully grown can vary depending on the breed and size of the dog.
Smaller breeds, such as the Chihuahua or the Yorkie, are generally considered to be fully grown by the time they reach 12 months of age. These breeds reach their full size and weight relatively quickly and do not experience significant growth after 12 months.
Medium-sized breeds, such as the Australian Shepherd or the Cocker Spaniel, are typically considered to be fully grown between 12 and 18 months of age. These breeds may continue to fill out and gain muscle mass after 12 months, but they will have reached their full size.
Large and giant breeds, such as the Great Dane or the Saint Bernard, can take much longer to reach their full size. These breeds may not be considered fully grown until they are 18 months or even two years of age. Large breeds typically have a longer growth period and take longer to reach their full size and weight.
It’s important to remember that just because a dog has reached its full size, it doesn’t mean that it has reached its full maturity. Many breeds continue to mature and develop emotionally and mentally even after they have reached their full size.
The general takeaway is that age at which a dog is considered fully grown can vary depending on the breed and size of the dog. Smaller breeds are typically considered fully grown at 12 months, while larger breeds can take much longer. It’s essential to remember that full maturity is not only based on physical growth, but also on mental and emotional development, which can take longer for certain breeds.
