Abstract

Dogs are one of the pets that have many useful benefits for humans. According to this, many people consider getting a dog, especially the Kintamani Bali dog, so it is important to know how the reproductive physiology of the dog works. This study aims to find a new simple method for determining the right time for mating seen from the vaginal pH and the correlation with ovary ultrasound in the Kintamani Bali bitches. This research is an observational study to determine vaginal pH levels and the connection with ovary ultrasound images in Kintamani Bali bitches during the proestrus phase to the estrus phase. Vaginal pH levels were checked every day from the first day of proestrus, when there was a blood discharge until the female ovulates. Ultrasound examinations were taken four times, when the first bleeding (proestrus phase), seven days later (end of proestrus) when the female accepted the male (estrus), and three days later (ovulation). The result showed that vaginal pH decreased from proestrus to estrus. At the beginning of the estrus phase, the average pH level was 7.1, while the highest was 7.8. Ovulation occurred on the 10th to 12th day from the first blood discharge, and the pH level was between 6 to 6.5 with an average of 6.2. after ovulation, the average pH level increased to 6.83. There is a relationship between the dynamics of vaginal pH and the ultrasound image of the ovaries in the Kintamani Bali bitches during the proestrus phase until estrus.
