  Breeding - Frequently Asked Questions




Females are required to be boarded in GDB kennels when they are in season, usually for 3 weeks. "When she is in season the vulva will be enlarged and blood stained fluid is passed. She may go off her food a few days, urinate more frequently when out on her walks and may be down and miserable when she is about to come into season." (from

"The first phase of the cycle is called “Proestrus” and is characterized by a swollen vulva, a bloody vaginal discharge, attraction of male dogs.  She flirts with the male but will not allow him to mount. The bloody vaginal discharge is what seems to lead to the misconception that the dog is menstruating. In fact, the blood comes directly from the walls of the vagina rather than the sloughing of the uterine lining as occurs in menstruation.

The second phase of the cycle is called “Estrus” which is characterized by the change in character of the vaginal discharge from bloody to “straw colored.”  At this time the female begins to allow the male to mount. It is classically the change from proestrus to estrus that ovulation occurs and the female is most fertile.

After the mating and the discharge is over, the period of “Diestrus” begins."  (Info from


The Breeding Department will determine an appropriate mate for the female based on temperament and family history. Females are generally bred once a year. Usually a different mate is chosen each time. "With a blood test, ovulation timing can be predicted to ensure a successful breeding. The actual breeding takes place during the female's initial rise in progesterone." (From

The dogs will be bred for 3 consecutive days during the female's initial rise in progesterone. The female will remain in the kennels until she is diestrus.

When picking up the dog from the kennels, you will be given an information packet on how to care for a pregnant dog, and encouraged to make an ultrasound appointment in the vet clinic.

The ultrasound and physical exam by the vet are the determining factors to prove pregnancy.
