WebArtificial insemination was applied to the dog because of vaginal cytology findings, anamnesis, and vaginal discharge. Epub 2021 Nov 29.

First, semen is collected from the male dog. According to another classification sperm abnormalities may be divided into major defects, negatively correlated with fertility, and minor defects, unassociated with fertility (Table 6) (Oettle, 1993). If the highly concentrated sperm-rich fraction is collected separately, the semen should be extended with saline or Tris-buffer to a concentration allowing the observation of particular, single sperm cells. In the dog, the volume of whole ejaculate varies between breeds (Table 4) mainly with animal size and is partially dependent on the volume of the third fraction collected, which constitute about 95% of the volume of the ejaculate in dogs (Farstad, 2010). WebTHIS EQUIPMENT IS SUITABLE FOR ANY SIZE OR BREED OF DOG! Your dogs first heat can show up from 6 months up to 2 years old.

The evaluation is performed under the objective of x20 to x40. The bitch is placed in a standing position on an examination table or on the floor (according to the size of the female). It takes a few minutes and could be mildly uncomfortable. The goal of breeding is to inseminate the bitch four days before ovulation and then every two days until the final insemination at two days after ovulation. It is also a good choice for older females, females with poor fertility, and those with uterine pathology. Both the laparoscopic approach and the laparotomy requires anaesthesia and good surgical skills. However, this method requires expensive equipment. Most often, artificial insemination with freshly collected semen is performed without fractioning the ejaculate, although for artificial insemination, only the second fraction is of interest (Thomassen & Farstadt 2009; Root Kustritz, 2003). The conception rates after intravaginal insemination with frozen-thawed semen are significantly lower when compared with the results of intrauterine insemination. The acrosomal status, which is frequently assessed for the estimation of the quality of the frozen-thawed semen, may be evaluated with the use of eosin-nigrosin, Giemsa, Trypan blue, Bismarck brown, Rose Bengal or Spermac stainings (Dahlbom et al.,1997; Dott & Foster, 1972; Watson, 1975).

Formerly turgid and smooth, the mucosa, becomes wrinkled and shrunked.

I would absolutely advise a vet visit as he may well need some anti inflammatories and antibiotics.

Most procedures used for semen deposition are neither detrimental to the bitch, nor interfere with animal welfare, and even allow protection against certain diseases. When performing AI we should be aware that vaginal deposition per se will negatively influence sperm cell survival and their transport in the female genital tract, and therefore impairs ability to achieve normal whelping rates and/or litter sizes. The optimal temperature for assessment of dog sperm cell motility is 39C. Some experts advise preventing her from squatting to pass urine for half an hour after insemination, to stop the semen being washed out of the vagina. During the second 10 days, the bleeding usually slows or stops completely and the female will be receptive again. 2015;8(4):191-196. doi:10.4103/0974-1208.170370.
