Hills ZD Prescription ULTRA Allergen Free Canine Dry is for the nutritional management of dogs with food allergy and food intolerance.

Food allergy and intolerance are potentially serious problems that can result in sensitive or irritated skin, coat and ear conditions or even digestive problems.

Hills Z/D ULTRA Allergen Free has been exclusively formulated with Hills Hydrolysed Protein System, a process that eliminates intact animal proteins and significantly reduces the possibility of an adverse reaction to food.

Reactions often occur as a result of ingesting beef, dairy products & wheat: Hills ZD ULTRA Allergen Free eliminates these from the diet.
