abstract
A four year old female pug was presented with patchy hair loss and intense pruritis. The dog was maintained on a commercial diet for more than a period of two years and was switched over to another commercial diet for the past two weeks. No history of tick or flea infestation was reported in the past six months. Physical examination of the dog showed several patchy areas of alopecia on the trunk, hind legs and perineum. Pustular lesions were seen on the ventral abdomen with crusts and scaling. Skin scrapping was negative for mites. Based on the clinical history of a severe cutaneous reaction which was seen after the introduction of new diet, physical examination and skin scrapping the diagnosis and treatment was focussed towards food allergy. A methodical approach with antihistamine, antibiotics, antifungal and a commercial hypoallergenic diet has provided a better clinical outcome in a period of six weeks.
