If you want to identify where your dog is in her heat cycle and the best time to breed from her, then cytology can give you perhaps the most accurate measure.
There are various ways to evaluate a dog's heat cycle, from progesterone tests to ovulation test pads to the Draminski Ovulation Detector.Dec 15, 2021.
A quantitative progesterone blood test is the single most accurate method for timing breedings.
The test is reported as a numeric result, usually ng/dl.
Combined with observing the behavor of the dog and bitch, vaginal cytology, ovulation can be pinpointed with great accuracy in most bitches..
CYTOLOGY OVUALTION TESTING FOR DOGS
A swab is taken of the cells lining the vagina and analysed under a specialised microscope which allows us to identify which stage of estrus your dog is currently in, if she has ovulated yet and if she is ready to mate..
TARGET Canine Ovulation Test is a rapid semi-quantitative ELISA test on a membrane for the visual estimation of the Progesterone level in plasma or serum of the bitch.
Its main use is to determine and monitor the period of ovulation to predict the correct time to mate..
The results showed a marked heterogeneity in the identification of vaginal cells and assessment of the time in relation to ovulation
This heterogeneity supports the opinion of survey participants that vaginal cytology alone is not a valid tool for determining the day of ovulation
Dogs ovulate 5-7 days prior to the onset of diestrus (7-9 days after the preovulatory LH surge), and hence, gestation length is usually 57 + 1 day from the onset of diestrus day 1
The period of behavioral estrus is variable, and often extends up to several days before and/or after cytologic estrus
It is most frequently used for supporting breeding management, high-risk pregnancy monitoring and determination of the time of parturition
To learn more about how and for what reasons veterinarians interested in small animal reproduction perform canine ovulation timing, an online survey was conducted in 2017
