Skin diseases and the effect of using vitamin A,D3,E in supporting treatment of skin diseases caused by Demodex and fungus in dogs

Abstract

The study was conducted on 2340 dogs at a veterinary clinic located in District No.9, Ho Chi Minh City in order to identify the groups of skin diseases, the factors related to the skin diseases, and to evaluate the effectiveness of using vitamin A,D3,E in supporting treatment of skin diseases caused by Demodex and fungi in dog. The studied result showed that the skin infection rate in dog accounted for 17.73%, of which itching symptoms occupied the highest rate (89.87%). Besides, there were other clinical signs, such as: erythema, alopecia, increasing pigmentation, hyperkeratosis, seborrhea, pustules, dermatitis, etc. The results of laboratory diagnoses indicated that the infection rate with Demodex canis was 15%, with fungi was 15.62% and with Sarcoptes scabiei was 1.25%. However, the combined infection rate with two or more caused agents was relatively high. The skin diseases suspecting due to allergy, nutritions and other unknown reasons also accounted for the high rate. The factors, such as age, breed, gender, kind of food, care of skin and hair were related to the rate of skin diseases in dogs. The highest infection rate with ecto-parasites in dog was 34.88% for the age group from 1 to 2 years old and 26.22% for the dogs without bathing. The highest infection rate of dog with fungi was 29.26% at the age group over 5 years old. The infection rate of dog with atopic dermatitis was 32.55% at the age group from 1 to 2 years old, 22.58% for the exotic breeds and 25.61% for the in-door raising dogs. The highest infection rate of dogs with skin diseases suspecting due to malnutrition was 31.7% at the age group over 5 years old, and 24.28% for the thin dogs. Besides, the infection rate of dog with atopic dermatitis and skin diseases suspecting allergy and malnutrition was 42.5%, higher than that of the dogs feeding with home made food and 40.42% for the out-door raising dogs. The result of using vitamin A,D3,E in supporting treatment of skin diseases caused by Demodex, fungi in dog showed relatively high effect.
