Spring now occurs earlier and allergy season lasts longer in most climates than it did decades ago. While people suffer from itchy eyes, runny noses, and scratchy throats, pets are affected too — but their symptoms look different. Most pets' allergy symptoms manifest as red and itchy skin rather than sinus and respiratory issues. They scratch persistently, which can lead to sores, redness, hair loss, and infections.
Many pet parents assume their dogs and cats are protected from allergen exposure by living indoors. Unfortunately, this is not the case. Our homes are not sealed environments — indoor air quality mirrors outdoor air quality almost exactly. There is no way to fully shield a pet from environmental allergens.
Recognizing Allergy Symptoms in Dogs and Cats
With the help of your veterinarian or a veterinary dermatologist, you can find the right treatment plan for your pet. Most dogs and cats with environmental allergies — a genetic condition also called atopy — begin showing symptoms at a young age, typically between 1 and 4 years.
In dogs, common signs include biting the paws, licking the belly, rubbing the face on carpets, couches, or furniture, and scratching until sores develop with hair loss. Some dogs perform a "carpet shuffle," rubbing their backs along the floor.
Cats can present with more unique skin symptoms when allergic, including fine pinpoint scabs or large plaque-like lesions on the belly, legs, lips, or even inside the mouth.
The more severe the itching, the more likely your pet is to create sores and experience hair loss, which can lead to infection and a strong odor if untreated. If any of these symptoms occur, contact your veterinarian.
Developing an Allergy Treatment Plan
Your veterinarian will first rule out commonly missed itchy skin conditions that can be mistaken for environmental allergies, such as contagious mite infestations (scabies), flea allergy dermatitis, and food allergies. Once these are eliminated, they will develop a protocol individualized for your pet. Effective management centers on three pillars: decreasing itchiness, preventing allergic flares, and restoring the skin barrier.
1. Decreasing Itchiness
Reducing or eliminating itchiness is the first priority. Prescription medications for dogs and cats, including steroids, can provide relief. Your veterinarian will help choose the best option for your pet. However, allergic disease is genetic and incurable — once anti-itch medication wears off or runs out, itching will return. Consistency in treatment is essential for preventing symptoms such as hair loss and infection from recurring.
2. Preventing Allergic Flares
Anti-itch medications treat the symptom of itching without reducing the underlying allergic response. Immunotherapy (allergy vaccines) addresses this by gradually desensitizing your pet to the allergens they react to, making them less reactive when exposed in their daily environment. Immunotherapy is determined by intradermal or serum allergy testing that identifies your pet's specific allergens. It can reduce the need for chronic medications and helps prevent worsening of allergic symptoms over time. Anti-itch medications can be used while waiting for immunotherapy to take effect. Improvement can often be seen within the first few months but may take up to 9 to 12 months in some pets.
3. Restoring the Skin Barrier
The skin barrier is responsible for keeping allergens and microbes out, but it is inherently defective or damaged in allergic animals. This makes them more susceptible to infections and allows allergens to penetrate the skin, leading to further inflammation and increased itching. Restoring skin barrier function can be done through both topical therapy and oral supplementation. Oral supplementation follows an "inside-out" approach, adding back the healthy building blocks of the skin. Topical therapy removes allergens from the skin surface, restores moisture and fatty acids, and reduces the presence of microbes.
DermaBliss Advanced Allergy Health Chews provide nutritional support with ingredients designed to support skin health from the inside out. For topical care, the DermaBliss collection includes shampoos and sprays formulated to support skin barrier function and manage allergy-related skin concerns. Dogs with allergy-related ear infections may also benefit from OticBliss ear care products to help manage ear discomfort.
Working With Your Veterinarian
Although allergies in pets can be frustrating, working with your veterinarian or veterinary dermatologist can help you get to the root cause and develop an effective management plan. They can recommend both prescription and over-the-counter solutions to help your pet feel comfortable again.
