Animal B-ultrasound diagnostic technology can be used to identify ovulation in female dogs. This method has been used as an important auxiliary means to determine the ovulation time in Germany.

Perform animal B-ultrasound monitoring on female dogs once. If no developing follicles are found, they can be checked again the next day until the follicles rupture and ovulate. An average of 5-6 examinations are required, and this method is more accurate. Mature follicles are round or oval in shape, with a diameter of 6-9 mm. There is an echo-free dark area inside the follicle, good brightness, and clear boundaries. 80% of mature follicles can see the cumulus structure; a sound-transmitting ring appears around the follicle. After ovulation, the follicle disappears or shrinks in size, and a light spot appears inside, which disappears completely in 1-2 days. Animal B-ultrasound detection of ovulation is relatively safe, with the advantages of being economical, non-invasive, intuitive, and highly repeatable. It not only provides a reliable method for monitoring ovulation for clinical female dogs, but also has important significance in observing the dynamic changes of the ovaries during the ovulation cycle.

At present, we usually solve the problem of dog reproduction by increasing the number of matings during the estrus period according to the time of vaginal bleeding of female dogs. In foreign countries, the ovulation time of female dogs is determined more by combining vaginal cytology, animal B-ultrasound examination and progesterone detection methods to more accurately determine the ovulation time of female dogs. my country should learn from advanced foreign research methods to improve the domestic technical level of detecting the ovulation time of female dogs during estrus. Only by correctly grasping the ovulation period of female dogs can timely mating be achieved to improve the conception rate and fertility. Reproduction is the foundation of the development of the dog industry, and its level is an important indicator of the quality of breeding work. It can be seen that the accurate determination of the ovulation time of dogs is of far-reaching significance.
