Itchy Dog Days: Understanding Atopic Dermatitis in Dogs

Does your dog lick their paws, rub their face, or scratch endlessly at their ears or belly? If so, you’re not alone. Many pet parents in El Paso, TX find themselves watching their pups suffer through allergies that just won’t quit. At TLC Animal Hospital, we often diagnose these symptoms as signs of atopic dermatitis (aka atopy) - a lifelong but very manageable skin condition.

What Is Atopic Dermatitis?

Atopic dermatitis, also called atopy, is an allergy to environmental substances like pollen, plants, dust mites, mold, insects, or even other pets (though not common, dogs can be allergic to cats!). It usually appears between 1–3 years of age and causes intense itchiness, especially around the ears, face, feet, armpits, and belly. 

How Atopy Affects Your Dog

Dogs with atopy may constantly scratch, lick, chew, or rub against furniture. Common secondary issues include ear infections, red skin, or bacterial and yeast skin infections.  These infections often worsen the itch.  Itchiness can disrupt sleep, behavior, and even your dog's trainability.

Diagnosing the Itch

Atopy is often a diagnosis of exclusion. Before confirming atopy, we’ll recommend ruling out flea allergies, food sensitivities, and skin parasites. Allergy testing via blood or intradermal methods can help identify environmental triggers.

Let’s Get That Itch Under Control!

There’s no cure for atopy, but there are many ways to manage it. TLC Animal Hospital offers personalized treatment plans using a combination of the following:

• Cytopoint – An injectable monoclonal antibody that targets IL-31, a key itch-causing molecule. It’s fast-acting, safe for dogs of any age, and lasts 4–8 weeks. Learn more at https://www.zoetispetcare.com/products/cytopoint

• Apoquel – A daily oral tablet that controls itching and inflammation by blocking allergy-related cytokines. It starts working within 4 hours and is suitable for dogs over 12 months old. Learn more at https://www.zoetispetcare.com/products/apoquel.

• Zenrelia – A daily oral tablet that controls itch associated with atopy in dogs.  It is only suitable for dogs 12 months of age and older.  Per the label, it should not be used within 4 weeks before or after vaccine administration. 

• Cyclosporine (Atopica or Cyclavance) – A daily oral pill or suspension that works to modulate the immune system to treat allergies (as well as other inflammatory or autoimmune diseases).  Maximum effect may take 4 weeks to 4 months to achieve. May cause temporary upset stomach symptoms when its first started. This can often be prevented by giving the medication with food initially or giving the capsules frozen..

• Steroids (prednisone, prednisolone, dexamethasone, Depo-Medrol, etc) – Steroids are generally very effective for reducing inflammation and itch, but should be used cautiously as they can be contraindicated with certain concurrent health conditions and medications.  Steroids can also commonly cause panting, increased thirst, increased urination, and increased appetite.  With long term use pets may experience adrenal suppression, skin and coat thinning, weight gain, suppressed immune function, secondary infections, and other “Cushing’s” like symptoms.  If used, steroids should ideally be given short term and gradually tapered to discontinue.

• Allergy Testing & Immunotherapy – Custom allergy shots or sublingual drops can desensitize your dog to allergens over time.  These are formulated with input from a board-certified dermatologist after skin or blood allergy testing has been performed to identify allergy triggers. Immunotherapy is the only treatment that has the potential to “cure” atopy (though some dogs may have only a partial response, and life-long immunotherapy is often recommended to prevent relapse). Full response may take 6 to 18 months to achieve, so patience and other strategies to control allergic signs in the short-term are still needed.

• Topical Therapy – Medicated shampoos, conditioners, sprays, or wipes help soothe and repair the skin barrier, wash away allergens, and prevent flare-ups.

• Fatty Acid Supplements, prescription skin diets, and antihistamines – Support overall skin health and offer mild symptom relief.
