This study assessed the most suitable behavioral test for discrimination of the odor of female dog urine during estrus and anestrus, to identify chemical compounds acting as female pheromones. Twelve male dogs were used for testing. Urine samples were collected from 16 females in estrus, 5 females...

The effects of gonadotropin, serum and follicular fluid on the in vitro maturation of canine oocytes were examined. Additionally, spindle size and spindle migration in MI-stage oocytes derived by in vivo or in vitro maturation were evaluated for the first time. Mature oocytes collected from beagle ...

The cardiovascular parameters of canine bitches were assessed during the estrous cycle. A total of eleven mongrel female dogs were enrolled in a longitudinal prospective investigation. Six animals were bred during the study and were assigned into group I, in which evaluations were performed during...

Growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15) play important functions in follicular and oocyte development in many species. This study evaluated the dynamic expression of GDF-9 and BMP-15 in canine follicles cells using flow cytometry analysis. Follicular cells ...

Superoxide dismutase (SOD) and glutathione peroxidase (GPx) are two important antioxidant enzymes involved in tissue homeostasis by protecting cells and tissues from an accumulation of reactive oxygen species. Information concerning antioxidant enzymes in the canine uterus is almost inexistent....

The study was conducted to investigate the success of inducted estrus and to track the hormonal levels during the estrus cycle, pregnancy and post-parturition in dogs. Ten females, aged 2-3 years and weighted 18-22 kg, were kept in cages at the College of Veterinary Medicine-University of Baghdad. ...

Bitches are monoestrous animals, and differs from other domestic animals due to hormonal profile of estrus cycle. Serum progesterone level increase rapidly during preovulatory LH surge. Oocyte maturation, follicular growth, ovulation, steroidogenesis, and luteolysis are physiologic process of...

This study aimed to assess the mechanisms of semiochemical signal detection in dogs. In the first experiment, five males were exposed to volatile semiochemicals emitted by a live female in estrus and the female's urine sample collected during estrus. The odor of canine food and clean air were used...

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...
