These medications can cause more than one egg to be released, which can result in more than one embryo developing and implanting. The semen does not need to be washed (seminal fluid removed) before this procedure. WebFrom the sounds of it, I would guess this dog is pregnant.

Do not push on the abdomen. Consequently, follicular dynamics evaluation through ultrasonography (US) in dogs is still experimental and must follow a very precise protocol, which accuracy increase with the use of frequent examinations. Your dogs first heat can show up from 6 months up to 2 years old. OVULATION TIMING Usually they appear as round to slightly triangular anechoic structures, sometimes slightly flattened, giving a honeycomb aspect to the ovary (Figure 2). The penis and collecting cone are firmly held in place with the collectors hands, stimulating the constriction of the female during a normal breeding. If the ejaculate has a very small volume, it may be diluted with semen extender, to facilitate its handling during insemination procedures. A positive diagnosis can be made as early as three weeks depending on the equipment and patient. In an ideal situation where everything goes just as it is supposed to according to all the latest science, a dog should not bleed after mating because she wouldnt mate until after the 9th dayof her proestrus stage or the 1st day of her estrus stage, and by then, her bleeding should subside. This should induce the vagina to begin contracting, which helps move the semen into the uterus. Once prepared, the semen can be deposited either in the vagina just in front of the cervix or just inside the uterus. Estrus is the fertility stage, and it lasts about 9 days. The majority of European centers working on small animal reproduction prefer transcervical intrauterine insemination (TCI) due to reasons associated with animal welfare.

For bitches less than 10 pounds (5 kg) 1.5 to 3 mls of semen are required per insemination. Except for those females, the AI catheter should be further introduced until it reaches the paracervical area, which can be palpated as a 1- to 2-cm-long, firm structure that ends at the cervix (a firm, rounded to ovoid structure, freely movable). sharing sensitive information, make sure youre on a federal In a dog, the bleedinghappens before her fertile stage.
