Physical examination revealed abdominal effusions and presence of abdominal mass. On detailed examination, blood tinged exudates could be aspirated from the abdomen (haemo-abdomen), which was positive for protein test. Wet film examination of the peripheral blood taken from the ear tip was found negative for any moving parasites. Severe ascites limited the diagnostic quality of abdominal radiography. On ultrasound scanning, the ovarian tumors were fount to be large, contained 1. MVSc Scholar, College of Veterinary and Animal Sciences, Mannuthy 2.

DIAGNOSIS Diagnosis was made from the history, clinical signs, haematologic investigations, radiographic examination and ultrasound scanning and the disease was diagnosed as an ovarian tumour. TREATMENT Treatment adopted was removal of tumour by ovaro-hysterectomy. In addition, chemotherapy is advisable to reduce the chances of re occurrence. Anaesthesia and control Anaesthesia was induced after premedicating with 0.4ml Glycopyrrolate and 0.4ml Xylazine hydrochloride and maintained using 1.6ml Ketamine hydrochloride. The dog was controlled on dorsal recumbency. Preparation of the site Site of incision - midventral from a point, behind the umbilicus backwards along the midline, over a length of 5 inches. The site was shaved, scrubbed with savlon, mopped dry with cotton and painted tincture iodine over the site to make it aseptic. Draped the midventral area of the dog exposing the site of incision.

Surgical Technique Incised the skin on the midventral site. Divided subcutaneous tissue on midline to expose linea alba. Incised the linea alba to its full thickness and exposed the abdominal viscera. Retracted the laparotomy edges using tissue forceps. Exposed the uterine horns, ovary and the bursa. Large, numerous neoplastic growths could be identified in both ovaries. Anterior ovarian ligament was cut and anterior utero-ovarian vessels are ligatured. The ovarian bursa is cut across its middle to expose the ovary. The ovary was disconnected from its anterior attachment. After both ovaries were freed in this manner, the posterior uterine arteries were ligated and cut in level with the cervix. The broad ligament of uterus is torn to liberate the uterine cornua. Applied two clamps anterior to the cervix and cut in between them to finally disconnect and remove the uterus with the ovaries. The stump was also ligated. Simple continuous sutures using catgut no. 2 were used to close the wound. Abdominal incision was closed with simple continuous double row with lock stitch for linea alba. The skin was sutured using nylon in horizontal mattress pattern. Applied tincture benzoin gauze to prevent bleeding over the suture line

Animal made a uneventful recovery and was presented in the veterinary hospital on 7th post operative day for suture removal. DISCUSSION
Ovaries with large tumour mass Post operative care given with Inj. Ampoxin and Inj. Taxim intravenously for 5 days.
Ovarian tumours are uncommon in bitches, which accounts for approximately 1 percent of all neoplasms. Ovarian tumors are prone for metastasizing (spreading), and some are capable of producing hormones. The peak incidence of epithelial tumors is between 4 to 15 years, with a predisposition among Pointers for epithelial tumors.
(Withrow and Susaneck, 1986). In this case, the age of affected animal is 9 years. Except for teratomas, ovarian neoplasms are found in middle aged to older animals. Breeds like Boxers, German Shepherds, Lhasa apso, Pomeranians, Yorkshire, English Bulldogs to be at an increased risk for granulosatheca cell tumors, a type of sex cord stromal cell tumour. In this case, a Pomeranian bitch is affected. There are three kinds of ovarian tumors in bitches-Epithelial tumors (skin/tissue), Germ cell tumors (sperm and ova) and Stromal tumors (connective tissue). The most common type of ovarian tumor in dogs is ovarian carcinomas. (Moulton, J.E.1978). In ovarian tumors like epithelial tumors, granulosa cell tumors, dysgerminomas, teratomas and germ cell tumors the clinical signs includes malignant ascites ,fever, anorexia, weight gain/loss and pleural effusions, in case of thoracic metastasis. Lack of sexual heat and menstruation, persistent
estrus, cystic endometrial hyperplasia/pyometra complex and squamous metaplasia of uterine mucosa, vulvar and vaginal hyperplasia, sanguineous vulvar discharge, secondary sex organ changes like gynecomastia, receptivity to male dogs are also seen. Ovarian tumors are generally treated with ovariohysterectomy. (Morrison, W.B.1990). For treatment for metastatic ovarian carcinoma, since most result in carcinomatosis, intracavitary cisplatin 2 (50 mg/m every 3 weeks for five to six treatments) is recommended which has survival times ranging from 6 months up to 5 years.
