Eleven Atlas Shepherd bitches of 4 years old, weighing between 15 and 16 kg who had an end stage of metestrus, have received treatment with bromocriptine, available in medicine human (Parlodel® 2.5 mg breakable tablet box of 30 tablets) orally to anticipate estrus. The dosage adapted for the bitches was 20 μg/kg body weight corresponding to 0.02 mg/kg twice daily. The return of heat was detected by clinical detection of vulvar losses and confirmed by the reading of vaginal smear and the ultrasound of the ovary to the canine clinical pathology of Veterinary Institute Ibn Khaldoun University of Tiaret between March 2016 and January 2017. All the bitches selected for this study were in good health and did not show any genital infection or pathology of their ovaries during their clinical examination. The aim of this study is to see if bromocriptine can be used to anticipate a return to heat outside its usual indication for the treatment of late anestrus in dogs.
