Quakers Hill Veterinary Hospital has a reproductive lab to help maximise breeding success. We are experienced in interpreting your dog’s cycle, ultrasound pregnancy diagnosis, artificial insemination including surgical implants, and handling bitches and their puppies pre- & post whelp.
Timing is crucial & is generally the biggest factor in a successful mating. Two methods are used to determine the optimal mating time:
- blood progesterone levels – sampling prior to ovulation is the most accurate thus it is best to test blood progresterone in the early to middle sections of the heat. Results return within 90 minutes. It is important NOT to mix results from a miniVidas machine and an Immulite machine as the parameter ranges are very different.
- vaginal cytology – the cells lining the vagina can approximate early heat, oestrus or post oestrus.
Days in season, vulval discharge colour, vulval size and male interest are helpful indicators but not accurate.
