Male golden retriever dogs are generally ready to mature when they are one and a half years old, but the best breeding time is after 18 months. Female dogs are best bred when they are 2 to three years old. The puppies obtained at this time are the best. .

1. Female dogs in estrus should be carefully guarded to prevent them from being secretly bred with unselected male dogs, which will affect the quality of the offspring; male dogs are not allowed to go out to look for female dogs in estrus, otherwise they will easily be infected with diseases, or be killed by other dogs due to competition for mates. Bite from a male dog.

2. Breeding should be carried out in a quiet and clean place. Except for the dog owner, other people should not be allowed to watch or make noise.

3. Do not drink water or engage in strenuous exercise immediately after breeding. The male and female dogs should be allowed to return to the kennel for a brief rest.

4. Although female dogs can reproduce twice a year, too many births will affect the physical constitution of both the female dog and the puppies. Depending on the age and health of the female dog, it can be determined whether it is more appropriate to breed three litters in two years or one litter in one year. Female dogs over 9 years old are generally not suitable for breeding.

5. Male dogs should not mate frequently to avoid affecting their health and shortening their breeding life. Adult male dogs mate once a day and should take a day off every 3-4 days. Occasionally, they mate twice in one day, with an interval of more than 6 hours, and must rest the next day. The frequency of breeding between young male dogs and older male dogs should be reduced. When the number of breedings is increased as a last resort, nutrition should be strengthened to compensate. Male dogs over 12 years old should generally not be bred.

At the same time, it is best not to let the golden retriever lie down to prevent the semen from flowing out after the breeding. It is also best not to bathe the golden retriever. It is best to bathe the dog three days after the breeding.
