Three easy steps to a food elimination trial

A food elimination trial is the gold standard to diagnose atopic dermatitis

When you see the clinical signs of allergic dermatitis, do you first think of a food elimination trial as the gold standard to help diagnose the underlying cause? Allergy tests and medications can't replace a diagnosis. Encouraging pet owners to try a food elimination trial supported by Royal Canin® Ultamino® nutrition helps you see beneath the surface signs.

Recommend Ultamino® for nutritional support while you protect the integrity of the food elimination trial*

Our extensively hydrolyzed protein and balanced nutrition makes Ultamino® ideal for an 8-12 week food elimination trial. Did you know:

  • To hydrolyze a protein means cutting its molecular size into smaller pieces
  • Hydrolyzed proteins reduce the risk of triggering allergic reactions
  • Our stringent production process reduces the risk of food allergy triggering elements ending up in our products

*Exclusive feeding with Ultamino®; no treats, chews or leftovers

After 8-12 Weeks, conclude and introduce a dietary challenge

Instruct pet owner to reintroduce original diet in a small portion (10–20%) mixed with Royal Canin® Ultamino®. If clinical signs reappear, the diagnosis may be an adverse food reaction.

For long-term nutritional management of an adverse food reaction (food allergies), recommend Royal Canin® Ultamino® or Royal Canin® Hydrolyzed Protein range.

What if your patient has atopic dermatitis?

Atopic Dermatitis (AD) is the pruritic inflammatory skin disease that results from the genetic predisposition to develop allergies to environmental allergens. These can include pollens, molds, dust, and house mites.

Royal Canin Skin Support® is high in levels of omega-3 fatty acids, which can help reduce inflammation. It also contains curcumin, aloe vera, vitamin C, and taurine, which can help support healthy skin generation and accelerate the healing process. A blend of B vitamins and amino acids are included to help maintain a healthy skin barrier. Royal Canin Skin Support® can also be used to manage cases long-term.
