Reasons for Dog Breeding Lock

When normal dogs mate, ejaculation begins a few seconds after the male dog’s penis is inserted into the female dog’s vagina, and then the male dog’s corpus cavernosum becomes embolized. This embolization state The time usually lasts for 6-20 minutes. This phenomenon is determined by the special structure of the reproductive system of male and female dogs. If the locking situation cannot be maintained or cannot be locked during mating, it is an abnormal phenomenon. The cause of failure to lock is generally related to both male and female dogs. Because the male dog's penis erects too early, it cannot be fully inserted into the female dog's vagina; the male dog's physical constitution is too weak, the frequency of breeding is too high, and the sexual desire is low, causing the penis to be unable to fully erect after insertion. The female dog is in abnormal estrus. During mating, the rhythmic contraction of the vagina is weak and the contraction strength of the vulvar sphincter is not strong enough to compress the dorsal vein of the penis. The penis cannot be fully erect or even if it can be erect, it cannot wrap the erect penis ball.
