HistaGuard Complex

Hill’s Prescription Diet Derm Defense canine formula is the first food designed to reduce environmental allergies by helping disrupt internal allergy responses and decrease signs of environmental allergies in dogs. Histaguard, a proprietary blend of egg, antioxidants and phytonutrients including quercitin to support ongoing normalization of immune response to allergens 24/7 is included in this diet plan, along with vitamin A and zinc essential for skin repair. Histaguard is an innovative combination of bioactives and phytonutrients designed to complement an egg source protein for maximum allergy avoidance, helping your dog live more comfortably with diet- and environment-sensitive issues. Histaguard forms part of an integrative multimodal approach to dermatological care alongside oral antibiotics and steroids; Histaguard assists in managing allergies that cause itching or chewing which could potentially lead to infections.

Omega 3 & 6 Fatty Acids

Hill’s Derm Defense is clinical nutrition designed to manage environmental sensitivities with an emphasis on skin health. The food contains an exclusive combination of bioactives, plant nutrients, omega 3 & 6 fatty acids and antioxidants to reduce symptoms associated with allergy, including itching.

Itching is often caused by allergic reactions and can result in significant skin damage such as reddening, inflammation and bleeding – creating a chronic issue for your pet’s quality of life. Hill’s Prescription Diet Derm Defense with HistaGuard and Omega 3 and 6 fatty acids is designed to improve skin health for dogs by soothing itching while simultaneously decreasing histamine response to allergens on an ongoing basis.

Roy, a 9 year old neutered cattle dog was suffering from seasonal skin allergies that required medication, food elimination trials and immunotherapy treatments to alleviate. Finally they decided to try Hills Prescription Diet Derm Defense; within six weeks the inflammation had subsided, his coat became shiny and his anal glands no longer required expression several times daily!


Zinc is an essential trace mineral essential to many biological functions in small quantities, including immune function, protein and DNA synthesis, wound healing, blood clotting and thyroid function. Zinc also plays an integral part in smell and taste sensation. Since zinc cannot be produced naturally in our bodies it must come from outside sources; most zinc stores in muscle and bone cells.

Studies indicate that people with low zinc levels are at an increased risk for infection. When taken immediately upon symptoms starting to show, oral zinc supplements could shorten duration and severity of cold symptoms significantly.

Zinc is an integral component of the superoxide dismutase (SOD) enzyme system, which works to neutralize free radicals within cells and alleviate oxidative stress. By increasing SOD activity, zinc can support healthy immune function.
