This report describes atypical chronic trypanosomosis in a three year male Spitz dog. Fever, lethargy and anorexia were the early presenting signs without any hemato-biochemical abnormality. Peripheral blood smear examination was non-diagnostic on three consecutive times. Trypanosma evansi was confirmed in the Leishman stained thin blood smears (moderate parasetemia) on fourth parasitological examination. Biochemical profile showed a remarkable elevation in total serum bilirubin (6.7 mg%) and activities of alanine amino transferase (ALT) (950 IU/L) and alkaline phosphatase (AKP) (1050 IU/L) after a month. Anemia, leucopenia, neutropenia, lymphopenia and thrombocytopenia suggestive of bone marrow depression appeared by about 73 days of presentation of case. A rapid complete clinical recovery occurred within a week after treatment with quinapiramine sulphate and chloride combination @ 3.5mg/kg bwt. Hemoglobin, leucocyte and thrombocyte count improved within six days, however, liver enzyme activity normalized slowly over three months.

TVT, also known as infectious sarcoma, venereal granuloma, transmissible lymphosarcoma or sticker tumour is a benign reticuloendothelial tumour that affects particularly mucosa of external genital organs and rarely internal genital organs in dogs of both genders. TVT is usually transmitted by coitus but also can be transmitted by licking, sniffing, biting,and scrabbling of the tumour affected area or through damaged skin of mucosa. Transmissible venereal tumour (TVT) is usually observed in stray animals live in tropical and subtropical lands. The affected animals are usually within 9-13 months of age and with high sexual activity. Tumour is frequently located in posterior vagina and vestibulovaginal junction. The averagechromosome count of TVT cells is 59 (57- 64). TVT specific antibodies were found in blood samples of affected animalswhich suggest that they may have a role in natural regression mechanism. The primary objective of tumour treatment is total elimination by surgery, radiotherapy, immunotherapy and/or chemotherapy. Controlling of the disease is very difficult because stray dogs are carriers.
