INTRODUCTION
Doppler ultrasonographic assessment of maternal
and foetal blood flow has become an indispensable diagnostic tool in veterinary obstetrics and gynaecology.
OBJECTIVES
To evaluate blood flow in uteroplacental artery(UPA), umbilical artery(Uma) and foetal abdominal aorta by measuring pulsatility (PI) and resistive indices (RI).
METHODS
Doppler examinations were conducted from fourth week of pregnancy at 10 d interval in twenty apparently healthy bitches of different breeds presented at University Veterinary Hospital, Thrissur, Kerala.
RESULTS
Throughout the study the UPA showed biphasic wave. Up to 40 days of gestation the UPA showed diastolic notch and from 41-50 days it completely disappeared. The PI and RI decreased significantly at 5 per cent
level between each 10 d interval. Similarly, the PI and
RI of Uma decreased significantly at 5 per cent level between each 10 d interval. The PI of foetal abdominal aorta increased significantly at 5 per cent level from ≤ 30 d to 31 – 40 d of gestation and thereafter it decreased significantly up to whelping. During early pregnancy the diastolic wave form was absent for Uma and abdominal aorta although at later stages both these vessels showed biphasic wave forms. The study also included the diagnosis of an incomplete abortion in a Rottweiler bitch by Doppler ultrasound and its critical management. Fourteen days from the date of the incomplete abortion of three puppies, the bitch whelped five healthy puppies.
CONCLUSIONS
The study demonstrated the potential applicability of Doppler Ultrasound in the management of abnormal pregnancy and predicting survival chances of neonates after whelping.

INTRODUCTION
Granulosa cell tumor is a primary ovarian neoplasia in the dogs which normally occur in elderly bitches with a median age of 12 years old.
OBJECTIVES
This study aims to present the discovery of granulosa cell tumor and ovarian cyst in young dog that they have not been reported yet.
METHODS
A 3-year-old, female Yorkshire terrier, was referred to Theriogenology Center at the Kasetsart University Veterinary Teaching Hospital, Bangkok, Thailand with clinical signs of vulva swelling for 2 years, since she had her first estrus until present time, and sign of abnormal frequent estrus every 2-3 months. Complete blood count examination, vaginal cytology and ultrasonography were performed. However, client denied to measure levels of serum sex hormones.
RESULTS
The results showed normal blood parameters from complete blood count. Vaginal cytology showed
about 20% cornification vaginal epithelial cells which
it indicated the influence of estrogen. Endometrial hyperplasia and cystic lesion on right ovary were found from ultrasonographic images. The dog was diagnosed as ovarian cyst on right ovary. Surgical correction was performed by ovariohysterectomy.
For further diagnosis, ovarian tissues from both ovaries were collected and submitted for biopsy. The histopathological results revealed that the dog had non-functional ovarian cyst, cystic subsurface epithelial structure, on the right ovary, and granulosa cell tumor with the present of monolayered clusters of cells and acinar to tubular pattern on the left ovary.
CONCLUSIONS
This is the case demonstrating the discovery of granulosa cell tumor and ovarian cyst in young dog which it is quite a rare case.
