Epidemiology of Canine <i>Wei Syndrome</i> and Its Hemorheology Characteristics

Abstract

Canine paraplegia is a common condition in small animal medicine, referred to as Wei Syndrome (WS) in Traditional Chinese Veterinary Medicine (TCVM). Common clinical manifestations encompass hind limb paralysis, motor dysfunction, muscle atrophy, and the absence of pain perception. WS is considered a difficult-to-treat disease in small animal practice. The objective of this study was to investigate the epidemiology of canine WS and the characteristics of hemorheology. A total of 53 dogs with WS and 53 healthy dogs were included in this study. A retrospective case-controlled study design was employed. Data regarding the gender, season of WS occurrence, breed, and age of dogs with WS, as well as hemorheology from dogs with WS and healthy dogs, were collected and analyzed using SPSS 27.0. The study findings revealed that male dogs were more susceptible to WS (77.36%, 41/53). WS cases occurred more frequently in Winter (33.96%, 18/53), and were commonly found in Poodle breeds (43.40%, 23/53). The most affected age of WS was between 3 and 6 years old (54.72%, 29/53). Except for plasma viscosity and fibrinogen, the hemorheology indices of canine WS were significantly higher than those of healthy dogs (p WS, with Winter being the season of high disease incidence. Abnormal hemorheology is a characteristic feature in dogs with WS, which should be considered during the treatment of WS.
