A 2 years old female beagle dog was examined because of the vaginal discharge and vaginal swelling at 7th day after mating. Abdominal ultrasonography revealed multiple follicular cysts on both ovaries. Also, the ratio of superficial cells was above 90% based on vaginal cytology. She was still in standing heat, with the tail deflected up and flagging when a male sniffed the vulva and attempted to mount. The dog was diagnosed with multiple follicular cysts by vaginal cytology, clinical signs and ultrasonography. The dog was treated with GnRH $50{\mu}g$ injection by intramuscularly. The sizes of the cysts were decreased two weeks after GnRH treatment, and then the dog delivered an offspring at 68th day after last mating. To confirm the stage of estrous cycle, we performed hormone analyses, retrospectively $Estradiol-17{\beta}$ concentration was 78pg/ml at diagnosis. Progesterone concentration was 6.9ng/ml at the last mating, and 66.9ng/ml at diagnosis. Therefore, we confirmed that follicular cysts was observed during diestrous stage in a beagle dog.
