In addition, breeders also are aware of the sanitary benefits associated with AI. Also, it is possible to save semen from valuable dogs into sperm bank to be used in next generations, after their death or the peak of reproductive age. Therefore, with spread of canine AI dog, breeders now may select stud dogs from all over the world to improve their kennel´ genetics, without transport-associated stress to the animals.
Hence, subsequent to the increase in the artificial insemination demand among dog breeders and owners and the broaden of the AI to preserved semen as a management tool in canine breeding, as through international exchange of frozen semen, inbreeding within breeds can be reduced. In past decades, progresses in the knowledge of canine physiology and new advances in canine semen technology allowed these services to become available worldwide. Artificial Insemination, one of the earliest techniques for assisted reproduction in animals and humans, took longer to be implemented in dogs due to species-specific particularities. In Artificial Insemination (AI) the semen is collected manually from a stud male and thereafter deposited (inseminated) in the female so that fertilization can occur in the absence of natural mating.
