In recent years, the successful development of dog breeding in Armenia has been hindered by various diseases, the most common of which is demodicosis. The spread of the demodicosis invasion in Yerevan is mainly due to the uncontrolled breeding of dogs, violation of sanitary and hygiene rules for dog rearing, and unauthorized sale and purchase of dogs. Lack of information about the disease among the dog owner and breeders is another important reason for the spread of the disease. Demodicosis in dogs proceeds with certain variations. The extent of invasion in autumn was 51.7 %, in spring – 34 %, in winter – (32.2 %), and in summer it was 18.5 %. The relatively low temperature of the external environment and the high relative humidity of the air are probably favorable conditions for the reproduction, growth, and development of causative agents of demodicosis in dogs. Studies have shown that the highest degree of demodicosis was observed among maternal livestock, and animals older than three months. The lowest degree of disease damage was observed in puppies up to three months old.
