In this study, a total of 167 clinical samples were screened by cytological examination, where 58 cases (34.73%) were found positive. The most common clinical signs recorded in the positive cases were pyrexia (102.8-105°F), mucopurrulent ocular and nasal discharges, hyperkeratosis of the digital pads, vesiculo-pustular dermatitis and nervous disorders. The variable neurological signs were chorea, paddling and cycling movement, muscle tremor, epileptic seizure with facial twitching. Occurrence of Canine Distemper (CD) was recorded highest in young dogs 0-6 months (55.17%) of age group. Season-wise more occurrence rate was recorded in winter (48.81%) months. Highest occurrence was also recorded in local non-descript (43.10%), unvaccinated (72.41%) and male (58.62%) pups. Canine distemper infection based on age, season, breed, sex and vaccination status were found significant (P<0.05) in statistical analysis. The present study suggests that regular annual vaccination against CD followed by booster dose can protect the dogs from infection.
