The observation of the cranial part of the vagina is performed for this purpose. The technique is especially useful Before implementing canine artificial insemination the owner and the clinician should be aware of the national or international regulations on semen import, if applicable, and of the local Kennel Club requirements respecting the use of canine AI and litter registration.

J Reprod Dev. 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. Table 8 condenses the available information on the AI schedules for fresh, chilled and frozen semen. The treatment option used almost exclusively is that of spaying (Ovariohysterectomy). doi:10.1002/14651858.CD000317.pub4, Boomsma CM, Cohlen BJ, Farquhar C. Semen preparation techniques for intrauterine insemination. The female recipient must be in heat (which occurs roughly twice a year) and about to or recently ovulated. eCollection 2022. When a woman bleeds, its after her fertile stage, and it means her ova were not fertilized and are being expelled. Restrictions to the use of AI in animals that never matted despite all physiological conditions met together to guarantee a successful mate, may respond to the ethical issue that demands for ruling out clinical reasons for AI, as an underlying unaware problem (congenital or behavioural) may exists. Surgical insemination technique have been proposed once for frozen semen or when the bitch presents an anatomical obstruction that prevents the insertion of the catheter or endoscope. Colombo M, Morselli MG, Franchi G, Schfer-Somi S, Luvoni GC. Independence America Holdings Corp. All Rights Reserved. Another common reason for artificial insemination in breeding programs is the geographic separation of the dam and sire. Symptoms to look for are vaginal discharge, tender abdomen, pus in the uterus, difficulty urinating, constipation, lack of appetite, weight loss, vomiting, lethargy, urinating more often, and drinking more often. Over 70 percent of the sperm need to have normal forward motility, which correlates to 150 to 200,000 normal appearing sperm per sample. Canine ejaculate consists of 3 fractions, with the first and third fraction consisting of prostatic fluid and the second being rich in spermatozoa (England et al., 1990) (Table 3).

If your dog has gone through years of estrus cycles without getting pregnant, her uterine wall has undergone changes ones that can promote pyometra, which typically occurs 2 weeks to 2 months after the last heat cycle. In this technique, an insemination pipette is used to deposit semen into the vagina just in front of the cervix. In fact, several countries (such as Norway, Sweden and the United Kingdom) refer to welfare concerns and discourage or even forbid the use of surgical procedures to obtain intra-uterine insemination (England & Millar, 2008; Linde-Forsberg, 2005b).

With AI using fresh semen, 62 to 100 percent success rate, With AI using chilled semen, 59 to 80 percent success rate, With AI using frozen semen deposited into the vagina, 52 to 60 percent success rate, With AI using frozen semen deposited into the uterus, 0 to 80 percent success rate. For these reasons this method of intrauterine insemination is becoming more popular. 2015;30(3):603-607.doi:10.1093/humrep/dev004. Some restrictions may exists to application of this method in different countries, that may compromise the registration of litters obtained without fulfilment of the legal requirements, such as previous evaluation of the situation or previous authorization of the local Kennel Club for the procedure. The bitch usually presents a relatively long follicular phase and considerable variability exists in the onset of estrous behavior and acceptance of the male, making it difficult to determine occurrence of the LH surge and onset of ovulation in this species unless specific methods for timing the ovulation and estimating the fertile period are used (Linde-Forsberg, 1991). Knowing exactly when to inseminate the female can be quite challenging and, if not done properly, fertilization will not occur.
