Scratching, licking and recurring ear infections can have several causes. Our Madison Heights team can examine your pet and discuss the next steps.

Chronic Itching Can Be Managed

Constant scratching, licking, or chewing makes your pet miserable and leaves you wondering what to try next. Skin problems usually take a step-by-step workup and some ongoing care to get under control.

At Madison Veterinary Hospital, we start by going over your pet’s symptoms, past treatments, and daily routine. If your dog has been scratching for weeks or your cat’s skin sores keep coming back, bring them in. Whether you’re in Royal Oak, Troy, or right here in Madison Heights, we’ll work on getting your pet comfortable again.

Signs Your Pet May Have an Allergy or Skin Condition

Skin problems can look a lot of different ways. The signs we see most often include:

  • Persistent scratching, licking, or chewing at the skin, paws, ears, or tail base
  • Red, inflamed, or irritated skin
  • Recurring ear infections
  • Hair loss or thinning coat
  • Flaky, scaly, or greasy skin
  • Hot spots or moist, weeping sores
  • Skin thickening or darkening over time
  • Rashes, hives, or raised bumps
  • Recurrent skin infections
  • Facial rubbing on carpet or furniture
  • Eye or nasal discharge alongside skin symptoms

These signs can come from allergies, parasites, infection, or hormone problems. An exam, often starting with a wellness visit, tells us which tests or treatments make sense.

Types of Allergies in Dogs and Cats

Environmental Allergies (Atopy)

Environmental allergies, also called atopic dermatitis, happen when the immune system overreacts to things like pollen, mold, dust mites, and grass. Both dogs and cats get them. Symptoms can be seasonal or year-round. Treatment focuses on controlling the symptoms and keeping your pet comfortable.

Food Allergies and Food Sensitivities

A true food allergy is an immune reaction to a specific protein, most often beef, chicken, dairy, or wheat. A food sensitivity causes similar symptoms without the immune reaction. Either one can cause skin problems, stomach and bowel problems, or both. The most reliable way to diagnose a food allergy is a strict elimination diet using a novel or hydrolyzed protein food for at least eight to twelve weeks.

Flea Allergy Dermatitis

A pet with flea allergy reacts to proteins in flea saliva, so a single bite can set off days of itching. Keeping every pet in the house on flea prevention, consistently, is a big part of managing it.

Contact Allergies

Contact allergies happen when the skin reacts to something it touches, like cleaning products, fabrics, plants, or something applied to the skin. They’re less common than environmental or food allergies but can be very uncomfortable, and finding the trigger often takes some detective work.

How We Diagnose Skin and Allergy Conditions

Getting the diagnosis right takes a step-by-step approach. At Madison Veterinary Hospital, a skin workup may include:

Thorough History and Physical Exam

We’ll ask when the symptoms started, how they come and go, and about your pet’s diet, home, medications, and past treatments. Those answers are often the most useful part of the visit.

Skin Cytology

Looking at cells from the affected skin under a microscope quickly shows bacterial infections, yeast overgrowth, and other problems that may be adding to or complicating your pet’s skin trouble.

Skin Scraping

A skin scraping lets us look for mites, like the ones that cause sarcoptic mange and demodex. Mites can cause serious skin disease and are sometimes mistaken for allergies.

Fungal Culture

For pets with hair loss, scaling, or round patches, a fungal culture rules out ringworm, which can spread to other pets and to people.

Dietary Elimination Trial

When we suspect a food allergy, we’ll guide you through an elimination diet using a prescription or novel protein food. It takes strict commitment for several weeks and there’s no shortcut, but it’s still the most reliable way to confirm or rule out a food allergy.

Allergy Testing

For pets with environmental allergies, testing can pinpoint their triggers when we’re considering immunotherapy. The results are used to make allergy shots or under-the-tongue drops that slowly make your pet less sensitive.

Treatment Options

The right treatment depends on the right diagnosis. Treatments we discuss and prescribe include:

Immunotherapy (Allergy Shots or Sublingual Drops)

Immunotherapy is made for your pet from their allergy test results, and it works to reduce their sensitivity to specific environmental allergens. It can take months to see improvement, and some pets still need other treatment to stay comfortable.

Targeted Medications

The right prescription for allergic itch depends on your pet’s species, age, health history, and symptoms. Your veterinarian can tell you whether medications like Cytopoint or Apoquel make sense for your pet, along with other options.

Treating Secondary Infections

Many allergic pets get bacterial or yeast skin infections on top of the allergy, and those have to be cleared up before we can really judge or manage the allergy itself. We treat them with medicated shampoos, sprays, or oral medication and recheck to make sure they’re gone.

Flea Prevention

For pets with flea allergy, keeping every pet in the house on prevention matters. We’ll help you pick a prescription product and show you how to use it.

Dietary Management

For food allergies, the treatment is simple on paper and harder in real life: cut out the trigger ingredient for good. We’ll help you find a long-term food that fits your pet and avoids their allergens, and our nutritional counselling can help with the switch.

When a Dermatology Specialist Is the Right Next Step

For pets with complicated, stubborn, or severe skin disease that isn’t responding to treatment, a board-certified veterinary dermatologist is sometimes the best next step. We’ll be honest with you about when that’s the case and handle the referral.

Working Through Ongoing Skin Problems

If past treatment hasn’t calmed your pet’s skin, we’ll go over what’s been tried and decide what to look into next. Follow-up visits let us see how it’s going and adjust the plan.

Bring a list of your pet’s foods, medications, and past treatments to the appointment. It helps us see the pattern and plan the next step.

Frequently Asked Questions

Can dogs outgrow allergies?

Most allergies need ongoing management rather than a one-time fix. Symptoms can change over time, so regular follow-ups help us see what’s working and adjust.

How long does a food elimination trial take?

A proper elimination diet takes at least eight to twelve weeks of sticking strictly to the new food. That means no treats, flavored medications, or table food with anything outside the diet. It’s a real commitment, but it’s the only reliable way to confirm or rule out a food allergy.

My dog only has symptoms in the summer. Is that still an allergy?

Very likely. Seasonal flare-ups are a classic sign of environmental allergies. Tree pollen, grass pollen, and mold each have their seasons, and many allergic dogs flare up in step with them, at least at first. Over time, many dogs start itching year-round as their allergies broaden.

Is my pet's constant ear scratching related to allergies?

It can be. Ear problems that keep coming back are often tied to allergies, but there are other causes too. An exam, and ear testing when needed, helps us treat the current problem and decide whether to look for an underlying cause.

Are there natural treatments for pet allergies?

Some supplements, like omega-3 fatty acids, have real anti-inflammatory benefits and can take the edge off allergy symptoms as part of a bigger plan. They’re rarely enough by themselves for moderate to severe allergies, though. We’re happy to talk about where supplements fit with other treatment.
