Ensuring a healthy reproductive system for female dogs is a prerequisite for preventing mating disorders. In terms of management, it is necessary to do a good job in reproductive system health care, especially care during estrus, mating, and delivery. Veterinary B-ultrasound should be used for regular examinations. Before mating, both male and female dogs should undergo physical examinations to see if they are in good condition, including nutritional status and whether they have external parasites. Dogs with problems are not allowed to mate to avoid parasites and other diseases being passed on to offspring. Before mating, the external genitalia of the male dog should be wiped with warm water to avoid reproductive system infection of the female dog due to unclean genitals of the male dog. Before the female dog is transferred to the delivery room when the due date is approaching, the delivery room should be thoroughly disinfected, and the female dog's breasts and vulva should be cleaned with warm water to ensure the cleanliness of the vulva before the female dog gives birth. Veterinary B-ultrasound examination should be used to avoid the occurrence of reproductive system diseases in female dogs.

Reasonable use of artificial assisted mating means. Assisted mating means that when the female dog has reached the breeding period, but cannot complete mating due to fear, jumping or biting the male dog, or the male dog's lack of sexual experience, or the size difference between the female dogs, the breeder can assist the male dog to insert his penis into the female dog's vagina. Female dogs that are mating for the first time often show escaping behavior because they have no experience and feel pain during mating. Artificial assisted mating can play a role in restraining and can also enable female dogs to have a correct mating posture, which is very helpful in cultivating good mating experience. Use veterinary B-ultrasound to check female dogs that are ready to mate before mating. For individual female dogs that bite male dogs and breeders and refuse to mate for the first time, the method of restraining them with a muzzle can be adopted, or the male and female dogs can be allowed to watch other breed dogs mate and gradually adapt to the mating method. When the size difference between male and female dogs is too large during mating, the terrain of the slope can be selected for adjustment.
