Achieving canine pregnancy by using frozen or chilled extended semen.
Successful artificial insemination in the dog requires good timing of the insemination, skilled collection and handling of the semen, and mastering of insemination techniques. The bitch should be inseminated late in estrus. The insemination dose should contain at least 150 to 200 x 10(6) spermatozoa. Fresh semen can be inseminated vaginally, whereas frozen-thawed semen should be inseminated into the uterus. Pregnancy rates of 84% with fresh semen and 69% with frozen semen are reported.
