Abstract: This study was carried out in Gemlik Military Veterinary School and Training Center to investigate the some parameters (estrus, mating season, tie at mating) related to mating in bitches. In this study, one-hundred mating data of bitches obtained during 2 years (2004 and 2005) were used. In this study, average tie at mating in year 2004 and 2005 for German Shepherd Dog (GSD), Labrador Retriever Dog (LRD) and Belgian Malinois Dog (BMD) were 16.61-17.52, 13.78-15.51 and 14.27-15.13 min, respectively and differences between breeds were significant (p<0.05). While mating season for LRD was at the end of the spring, it was in the begining of the summer for GSD and BMD. Dates of mating in year 2004 and 2005 were on days 12.7-15, 13.1-14.7, 9.9-11.2 of estrus and average service numbers were 3.8-4.2, 3.9-4.9, 4.1-4.7 times for GSD, LRD and BMD, respectively. As phenotypical correlations, it was determined that there were significant positive correlations between mating age and mating season and between mating season and tie at mating of bitches (p<0.01).
