Dermatological affections are among the one of the most common encountered problems in dogs. The present investigation was conducted to study the prevalence of different dermatological affections in dogs and haemato-biochemical alteration and therapeutic efficacy of moxidectin and ivermectin in canine demodicosis. The prevalence study was undertaken from January 2019 to December 2019. Total 2248 cases were recorded, out of which 613 (27.26%) cases were found dermatologically affected. The sarcoptic mange infestation was found to be most prevalent (31.48%) dermatological affections followed by ticks, lice, mite infestations, pyoderma and allergic dermatitis. Most of the skin disorders were recorded during rainy season (33.69%) followed by summer season (21.14%).The dermatological affections were more (54.49%)in males as compared to females (45.51%).The high (36.38%) prevalence of dermatological affections was recorded in dogs of age between 1-3 years and low (16.64%) prevalence was recorded in dogs of age more than 5 years. The hemato- biochemical study revealed the significantly decrease in Hb, PCV, TEC and albumin and significantly increase in TLC, neutrophils, eosinophils, total protein, albumin, ALT and AST in dogs suffered from demodicosis as compared to healthy dogs. The therapeutic study revealed that moxidectin and ivermectin were found equally effective against in canine demodicosis and complete recovery were observed on 14^th day after treatment.
