The age of sexual maturity in dogs varies with breed and size, and small dogs are sexually mature earlier than large dog breeds. The average sexual maturity of dogs is 11 months, 7-16 months for purebred dogs, with an average of 11 months, and 6-17 months for mutts, with an average of 9.5 months. However, the sexual maturity and physical maturity of dogs are not synchronized, waiting until the growth and development of the dog is basically completed before breeding, and it generally takes about 20 months for a dog to reach maturity, 12-18 months for female dogs and 18-20 months for male dogs. In addition to the breed and age of the dog, the dog’s physical condition and health, etc. also affect the dog’s reproduction, in the dog breeding period should also take extra care to avoid some unnecessary trouble.
