Study of Estrus Induction in the Female Dog by PMSG and HCG

Abstract

Our study, spread over four (4) months (February to June), aims at heat induction and monitoring within a population of 10 female dogs of different breeds (German shepherd, Rottweiler and Pit-bull). Aged from 2.5 to 4.5. Two of them were used as controls. To do this, we carried out the following investigations: Monitoring the sexual cycle of the female dogs, prior to heat induction, by gynecological and cytological examination (vaginal smears) to confirm the sexual rest phase (anestrus); hormonal induction of heat by PMCG and hCG; monitoring the induced heat by the vaginal smear method (Giemsa stain); and a breeding of female dogs in estrus confirmation of the pregnancy of the mated female dogs (palpation and ultrasound) by comparing the vaginal smears of the treated female dogs with those of the control female dogs. At the end of our study, the results obtained were encouraging, since we succeeded in obtaining the appearance of heat in 60% of the treated female dogs.
