A4 year old male Shi Tzu was brought to a veterinary clinic in Bharicharoen, Bangkok with a problem of skin disease which was unresponsive to any treatments for about 2 years. The dog han generalised skin erythema and greasy skin especially on all feet,face and both inner pinnae. On dorsum o by of the dog, there were numerous follicular papules and furuncles which spreaded to all areas. The dog had severe pruritus on both ear pinnae and hot spots with diameter about 2 cm on both cheeks were found. Cytology of both ear canals revealed a large number of cocci and small number of yeasts. Intracellylar cocci were found from cytology of skin. Mixed infestations of Demodex cornei (majority) and D. canis (minority) were detected in the same dog . By using hair plucking examination, D. canis were detected and by tape preparation technique from both inner pinnae, a large number of adult shot-tail Demodex mites were identified tentatively as Demodex cornei. Measurements of lengths of gnathosoma, podosoma, opisthosoma, total body length and body width of both Demodex spp. were done. Thirty adult D. cornei were measured, opisthosoma length was 62.50 - 102.50 microns (59.25 9.68 microns (n=30), body width was 32.50 - 42.50 microns (39.06 2.31 microns) (n=24).and total body length was 132.50 - 187.50 microns (156.92 11.12 microns) (n=30). Total body length of sixteen adult D. canis was 175.00 - 262.50 microns (217.83 30.06 microns) (n=15),body width was 37.50-47.50 microns (42.50 2.89 microns) (n=11). The ratio of mean of total body lengtn and opisthosoma length between D.canis and D. cornei were 1.39 and 2.49 respectively. The demodectic mangy dog was treated successfully with 3.3% lime sulphur daily oral ivermectin whtothe dosage of kg , and supportve tretments wiht antibioti and topical antimicrobial shampoo
