The skin is divided in three layers:Epidermis DermisHypodermis

• Epidermis:
• Dermis: is the vascular layer containing nerves, sebaseous sweat glands and hair follicles
• Hypodermis: a fibro-fatty layer providing energy reserves, heat insulation and protective padding.

• Thickest on the forehead, dorsal neck, dorsal thorax, rump and base of the tail.
• Thinnest on lateral surfaces of the auricula, axillary, inguinal and perineal areas and on the undersurface of the tail.

• Use diagnostic aid/methods

Close inspection, palpation and smelling of the skin and hair coat are necessary to identify and characterize lesions.

Symetrical: Hyperestrogenism
Asymentrical: RingwormLocalized: may be single like scales typical of chin acne in cats
Regional: may be restricted to certain regional areas; hookworm infection in dog limbs

Apply oil on the blade, microscope slide and lesion.
Scrapings must be deep enough to cause capillary bleeding over an area of 1-2 cm of an active lesion
After scraping, mix the accumulated debris on the blade into the mineral oil–Examine under microscope

This technique is recommended to find superficial ectoparasites, like the ones named before and to isolate yeasts such as Candida albicans fro the skin

• Intact pustules are ideal for culturing.• The hair is clipped over the lesion.• A 16 mm (22-25 g) needle is used to
cut a bit open the lesion• Material is placed to cultivate
