It is generally recommended that puppies be given birth to puppies after they reach the age of 12 months. Dogs generally reach sexual maturity around 8 months of age. When a dog reaches sexual maturity, it is ready to have children. However, it is not recommended to allow dogs to give birth at this time. Although the dog is sexually mature at this time, its body functions are not yet fully developed. Breeding too early will cause the female dog to be thin and slow in growth, and will seriously affect the physical health of the female dog.
It is generally recommended to breed the dog to have children after it reaches adulthood. The suitable breeding age for small dogs is generally 1 to 1.5 years old; the suitable breeding age for large dogs is generally around 2 years old. At this time, the dog's body functions have fully matured, which is the most suitable stage for breeding.
