How long does it take for a dog to mature?

The maturity of a dog varies depending on the specific situation, including the breed, feeding method, and environmental factors, which all affect the timing of maturity. Most small dogs reach maturity between 8-10 months, while medium-sized dogs take about 1-1.5 years, and large dogs need even longer, at 1.5-2 years.

If the owner wants to breed their dog, it is recommended to do so during the dog's second estrus period after maturity. At this stage, the dog's body and reproductive system have fully developed, making breeding safer and less harmful to the dog. The resulting puppies will also be more attractive.

For owners who do not plan to breed their dogs, it is advised to have them spayed or neutered after their bodies have matured. Doing so can more effectively prevent male dogs from engaging in territory marking and fighting behaviors. Waiting too long for neutering can lead to behavioral habits that are difficult to break, even after neutering. Additionally, neutering male dogs can prevent high-risk diseases such as perianal tumors and testicular cancer, while spaying female dogs can prevent common reproductive system problems like pyometra or ovarian cancer, as well as menstruation issues in female dogs.

Moreover, having a dog spayed or neutered after maturity results in better physical condition and faster recovery. Performing surgery before the dog's body is fully developed can divide the dog's nutrition into two parts: one for recovery and one for development, which can negatively affect both aspects. Furthermore, when a dog's body is fully mature, it enters its prime adulthood. The risk of anesthesia during this period is lower than in older dogs, and the dog's overall health is better, which can naturally reduce the risk of anesthesia.
