Constant scratching, paw licking, irritated skin, and recurring ear problems can make your pet miserable and leave you wondering what keeps triggering the problem. Cat and dog allergies can develop in response to environmental allergens, fleas, food ingredients, and other triggers, and the symptoms often look similar to other skin conditions.
At Acton Animal Hospital, our Acton, MA veterinarians evaluate the source of your pet’s itching and skin irritation so we can recommend treatment based on what is actually causing the problem. Whether your pet has seasonal itching, chronic ear infections, atopic dermatitis, or another skin concern, we can help them feel more comfortable.

What Are the Signs of Allergies in Dogs and Cats?
Allergies commonly affect a pet's skin and ears. While occasional scratching is normal, persistent or worsening symptoms deserve a closer look.
Signs your pet may have an allergy or another dermatologic condition include:
- Frequent scratching, licking, chewing, or biting at the skin
- Paw licking or chewing
- Red, inflamed, or irritated skin
- Hair loss or thinning fur
- Scabs, sores, or hot spots
- Dry, flaky, or oily skin
- Persistent skin odor
- Recurring ear infections
- Head shaking or ear scratching
- Redness between the toes or around the paws
- Repeated bacterial or yeast skin infections
How Are Allergies Diagnosed in Pets?
There is rarely one universal test that explains every itchy pet. Instead, your veterinarian will consider your pet's symptoms, medical history, lifestyle, diet, and the pattern of their skin or ear problems.
Depending on what we find, the diagnostic process may include:
- A complete physical and skin examination
- Ear examination
- Skin or ear cytology
- Testing for parasites or infection
- Evaluation of flea exposure and prevention
- A veterinary-directed food trial
- Additional allergy testing when appropriate
This step-by-step approach helps us distinguish allergies from infections, parasites, and other conditions that can cause similar symptoms.
How Are Allergies in Dogs and Cats Treated?
Treatment depends on what is triggering your pet's symptoms and whether secondary skin or ear problems are present.
Your pet's treatment plan may include:
-
Medications to control itching and inflammation
-
Treatment for bacterial or yeast infections
-
Ear medications when infections are present
-
Consistent flea and parasite prevention
-
Medicated shampoos or topical therapies
-
Dietary changes or a structured food trial
-
Allergy immunotherapy when appropriate
-
Long-term management for environmental allergies or atopic dermatitis
Because many allergies are chronic, treatment often focuses on controlling flare-ups, limiting exposure to known triggers, and keeping your pet's skin barrier healthy over time.
When Should I See a Veterinarian About My Pet's Itching?
Schedule an appointment if scratching, licking, chewing, or skin irritation becomes frequent, causes visible skin changes, or keeps returning.
You should also contact your veterinarian if you notice:
- Open sores or bleeding
- Significant hair loss
- Strong skin or ear odor
- Swollen or painful ears
- Persistent head shaking
- Moist or oozing skin
- Repeated skin or ear infections
- Itching that disrupts sleep or normal activities
Mild dryness and chronic allergic skin disease can look similar at first. If you're considering an at-home skin product, our article on coconut oil for dogs explains when it may help with minor dryness and when ongoing skin symptoms warrant a veterinary exam.

Frequently Asked Questions About Cat & Dog Allergies
Persistent scratching can result from environmental allergies, flea allergy dermatitis, food allergies, parasites, bacterial infections, yeast infections, or other skin conditions. Because several problems can cause nearly identical symptoms, a veterinary exam can help identify what is triggering your pet's itching.
They can be. Environmental and food allergies can cause inflammation inside the ear canal, making some dogs more prone to recurring yeast or bacterial ear infections. Dogs with allergies may also shake their heads, scratch their ears, lick their paws, or develop irritated skin.
Treatment depends on the type of allergy, the severity of your pet's symptoms, and whether an infection or another skin problem is also present. Care may include itch-control medications, topical treatments, parasite prevention, dietary changes, treatment for secondary infections, or allergy immunotherapy when appropriate.
It may help when a food allergy is contributing to the itching, but changing foods randomly can make the cause harder to identify. Your veterinarian may recommend a structured elimination diet using carefully selected ingredients for a set period of time to determine whether food is contributing to your pet's symptoms.
