Abstract

Among endo and ecto-parasite, canine demodicosis is one of the major infestations. It’s a severe skin infection which can occur at any age and alters various blood, biochemical and hormonal parameters in the body. The current study investigated the prevalence rates and pathological manifestations in various breeds of dog with respect to age and breeds. A total of 100 dogs suspected for canine demodicosis were selected randomly for canine demodicosis based on clinical signs. The confirmation was done by deep skin scraping and tape impression method. Over all it found prevalent up to 44% in the district Lahore. Moreover, “Pug dogs” found most susceptible to demodex mites (M=15.91%, F=13.64%). The second most infestation breeds were “Pointer” male dogs and “Dobraman” male dogs (6.82%). The lowest incidence rates were recorded in “Boxer”, “Terrier” and “Labrador” (2.27%). At the meantime, all age groups are found susceptible to demodex canis infestation. The TLC, MCH, MCHC, PCV, monocytes, basophils and neutrophils were significantly increased in infected breeds. Total proteins, globulins, aspartate aminotransferase and alanine aminotransferase were increased in infected breeds. The level of cholesterol, T3 and T4 were increased in infected breeds but only cholesterol level was found statistically significant.
