INTRODUCTION
Shih-Tzu is a brachycephalic breed and frequently suffers from respiratory distress. Chronic respiratory distress may cause of elevated pulmonary arterial pressure. Pulmonary hypertension (PH) is known as a negative prognostic factor for degenerative mitral valvular disease (DMVD) in small breed dogs.
METHODS
Sixty-three client-owned small breed dogs (BW < 10Kg) affected with ACVIM stage B2 DMVD were included. A full physical examination, noninvasive blood pressure measurement, blood checkups, electrocardiographic and echocardiographic examination were carried
out in all dogs. Echocardiographically, high tricuspid regurgitation (TR) velocity > 2.5m/s considered as PH. Dogs, except Shih-Tzus, with brachycephalic obstructive airway syndrome were excluded from this investigation. Dogs with right bundle branch block, tracheal collapse and primary/secondary lung tumors, positive reaction for circulating antigens of Dirofilaria immitis, and pulmonary stenosis were also excluded from this investigation.
RESULTS
The incidences of PH (TR > 2.5m/s) in Shih-Tzu, Maltese terriers and other small breed dogs were 72% (13/18), 30% (6/20) and 28% (7/25), respectively (P = 0.007). No significant differences in fractional shortening, LA/Ao (1.39 ± 0.17, 1.45 ± 0.16, 1.41 ± 0.15) were found. However, TR peak velocity (2.73 ± 0.98, 2.04 ± 0.73, 2.23 ± 0.87 m/s) was significantly higher in Shih-Tzus (P < 0.04).
CONCLUSIONS
Higher incidence PH was found in Shih-Tzu, compared with other small breed dogs with Stage B2 DMVD. Further studies of skull pattern in longterm management of DMVD are warranted.

INTRODUCTION
Ehrlichiosis, Babesiosis induced thrombocytopenia (TCP) are commonly encountered in small animal practice in India. Canine platelet transfusions are slowly gaining momentum in our country to counter bleeding diathesis.
OBJECTIVES
To prepare Platelet-Rich Plasma(PRP) from separate dog donors and transfuse PRP to the affected dogs with severe TCP with bleeding diathesis.
METHODS
Canine Platelet-Rich Plasma (PRP) was prepared using Triple blood bags. 350 mls fresh whole blood collected from separate donor dogs (n=38) and were centrifuged on a soft spin of 2000 x g for 10 minutes (braking time = 2 minutes, 30 seconds), the PRP was expressed into satellite bags and stored as 100ml single units at 24 °C for five days in the platelet agitator.
RESULTS
The mean Platelet Count was 5.0 (+/- 3.0) x 10 (10) platelets/PC (range, 3.3 to 6.4x 10(10) platelets/PC)
and the mean (+/- SD) platelet yield from WB to PRP
was 78 (+/- 13) % Hematocrit was 1 to 5% and PRP
was negative for fungal and bacterial culture. Severe Thrombocytopenic dogs with Platelet Counts (PC) below 25,000 cells were transfused and after 24 hours good increase in the Platelet Counts (PC)above 1,25,000 cells / cmm were recorded.
CONCLUSIONS
Thrombocytopenic dogs with PC below 25,000 cells/ cmm with petechiation, ecchymosis, purpura, epistaxis, haematuria, haemoglobinuria, melena were transfused with PRP to increase the platelet counts. During 2016- 2017, 28 severely thrombocytopenic dogs referred to the TANUVAS Animal Blood Bank, Madras Veterinary College, were transfused with stored or fresh PRP from separate canine donors provided immediate short term local hemostatic effects.
    OBJECTIVES
The aim of this study was to compare the incidence and severity of PH among Shih-Tzu and other small breed dogs with DMVD.
