Nutritional management is a simple but powerful tool in controlling the clinical signs of atopy in dogs. A recent double-blind
study compared the performance of three commercial veterinary diets in atopic dogs regarding pruritus, skin lesions, and overall
atopy severity and found that diet does make a difference.
Of the three diets compared (diet A, Iams® Veterinary Formulas Skin & Coat Response™ FP; diet B, ROYAL CANIN Veterinary Diet™ Canine Hypoallergenic HP 19™; diet C, Hill's® Prescription Diet® d/d® Potato & Salmon
Formula Canine), diet A was significantly more effective at managing pruritus, skin lesions, and overall atopy severity in
moderately to severely atopic dogs than diet B. Dogs fed diet C did not show significant differences vs. diet A in improvement
of the clinical signs.
The diets in this study varied in ingredient and nutrient composition; however, the study results of this and previous studies
suggest that the dietary omega-6:omega-3 fatty acid ratio may be important in managing the clinical signs of atopy (data on
file, P&G Pet Care, 2008).
