Definition of Infertility in Female Dogs
In the most general sense, infertility is the inability to conceive, maintain a normal pregnancy or produce living offspring. More specifically, infertility in female dogs refers to the failure: 1) to ovulate, 2) to cycle normally, 3) to accept a male dog, 4) to conceive, 5) to successfully maintain the pregnancy, and/or 6) to deliver viable babies at or near-full term. A bitch should be labeled as “infertile” only after she has been through a well-timed management breeding program and after the male’s fertility has been unequivocally established.
The causes of infertility in female dogs are highly varied. Fertility requires a normal heat cycle and ovulation of normal eggs (ova) into a healthy reproductive tract, followed by fertilization of those eggs by normal sperm that are successfully introduced into the female. There also must be successful implantation of the embryos in the uterine lining, normal development of the fetuses, successful maintenance of the pregnancy and a successful delivery of live puppies.By far the
Most bitches have their first heat cycle around one year of age, give or take a few months. Thereafter, they typically have about 2 heat cycles per year. After a successful breeding, pregnancy can be detected by a skilled veterinarian or breeder at about 4 weeks into the pregnancy by physical palpation (feeling) of the abdomen and pelvic area. This should not be done by an inexperienced person, as it could be quite dangerous to
Whenever a breeding does not result in a successful pregnancy, the fertility of both the male and the female should be assessed. In females, that assessment should include whether the problem was failure to ovulate, failure to conceive, failure of implantation, early embryonic death, fetal resorption, fetal mummification, abortion or something else. It can be challenging, at best, to identify the precise reason why a particular bitch did not conceive or carry a litter to
The primary goals of treating infertility in female dogs are to identify and rectify the underlying cause of the condition. In the majority of cases – but not all of them – the cause is ineffective breeding management practices. In other cases, the treatment must be tailored to a specific underlying medical problem. How to effectively manage a canine breeding program is a topic beyond the scope of this article.Bitches with vaginal or uterine infections
