If clinical signs are suggestive of flea allergic dermatitis, demonstration of the presence of fleas or flea dirt will help confirm the diagnosis. Parting the hair and visually inspecting for fleas may be sufficient for this; alternatively a flea comb can be used. Material obtained by combing may be placed on a moistened, light-coloured paper- brown material will "bleed" on the paper if it is indeed flea dirt.
