Pet Dermatology & Allergy Treatment in Kitchener

Skin problems are one of the most common reasons pets visit the vet, and one of the most frustrating. Without identifying the underlying cause, symptoms tend to come back. At Kingsdale, dermatology is one of our areas of clinical interest.

Why is my pet scratching so much?

Constant itching, licking, and chewing at the skin can have several causes. The most common ones we see in Kitchener:
🌿

Environmental Allergies

Reactions to pollens, mould spores, dust mites, or grasses. In the Kitchener-Waterloo region, allergy flares are common in spring and fall as tree and ragweed pollens peak.

🍗

Food Allergies

Usually a reaction to a protein source like beef, chicken, or dairy rather than grains. Food allergies cause year-round symptoms with no seasonal pattern.

🪲

Flea Allergy Dermatitis

Even a single flea bite can trigger a reaction in sensitive pets. See our preventative care page for flea and tick control info.

🧴

Contact Allergies

Reactions to specific materials, cleaning products, lawn chemicals, or plants your pet rolls in or walks through.

🦠

Secondary Skin Infections

Yeast and bacterial infections often develop when an underlying allergy disrupts the skin barrier. Treating the infection alone without addressing the cause leads to repeat episodes.

Worth Knowing

Many skin conditions look similar on the surface. Getting the diagnosis right before starting treatment avoids months of guessing and a pet that never fully feels comfortable.

Signs your pet may have allergies or a skin condition

Constant itching, licking, and chewing at the skin can have several causes. The most common ones we see in Kitchener:
  • Constant licking of the paws or belly
  • Scratching at the face, ears, or armpits
  • Red, inflamed, or thickened skin
  • Recurring ear infections
  • Hair loss or a patchy, thinning coat
  • Hot spots (acute moist dermatitis)
  • A musty or yeasty smell to the skin or ears
  • Rubbing the face on furniture or carpet
Cat Owners

In cats, skin problems can look different. Watch for over-grooming that leaves thinning patches, scabs along the neck and back, or miliary dermatitis (tiny crusty bumps scattered across the skin).

How We Diagnose Skin & Allergy Problems

We start with a full history and a detailed skin exam. We'll ask about when symptoms started, whether they're seasonal or year-round, which areas of the body are affected, and what you've already tried. Depending on what the exam shows, we may recommend one or more of the following:
1

Skin Cytology

A quick look at cells from the skin or ears under a microscope. This tells us whether yeast or bacteria are involved and helps guide treatment.

2

Skin Scrapings

Rules out mites (mange) as a cause of itching and hair loss. If your pet is on a flea and tick preventative, we may not need to perform skin scrapings as these products often target mites as well.

3

Allergy Testing

Identifies the specific environmental allergens your pet is reacting to. This forms the basis for allergen-specific immunotherapy, which is the closest thing to a long-term solution for environmental allergies.

We perform serum allergy testing at Kingsdale. For intradermal allergy testing, we refer to a veterinary dermatologist.

4

Food Elimination Diet Trial

The most reliable way to diagnose a food allergy. It involves feeding a single novel or hydrolyzed protein diet for 8 to 12 weeks with no exceptions. We'll walk you through it.

The Bigger Picture

We also factor in your pet's full history from their annual wellness exams, which helps us notice patterns over time and catch recurring issues early.

Treatment Options

We start with a full history and a detailed skin exam. We'll ask about when symptoms started, whether they're seasonal or year-round, which areas of the body are affected, and what you've already tried. Depending on what the exam shows, we may recommend one or more of the following:

Apoquel®

A daily oral medication that controls itch and inflammation quickly. Often used while a longer-term plan is put in place.

Cytopoint®

An injectable antibody therapy that targets the itch signal at the source. Works well for dogs with atopic dermatitis and typically lasts 4 to 8 weeks per injection.

Medicated Shampoos & Topicals

Helps manage secondary infections, reduce surface bacteria and yeast, and support the skin barrier. Pets bathed routinely during allergy season often have better symptom control.

Prescription Diets

For confirmed food allergies, a long-term hypoallergenic diet is often the most straightforward solution. We'll help you choose one, and you can reorder through our online vetstore anytime.

Allergen-Specific Immunotherapy

Allergy shots or sublingual drops formulated for your individual pet based on testing results. Builds long-term tolerance to specific allergens over 12 to 18 months.

Antibiotics

Pets with allergies have a defective skin barrier, which allows normal surface bacteria to gain access. All infections need to be addressed before we can expect success from anti-allergy therapies.

Ear Infections & Allergies

More than one ear infection in a year is almost always an allergy problem. The infection is just what you see on the surface. Underneath, something is keeping the ear canal irritated enough that yeast and bacteria keep coming back.

Treating each flare-up helps. It doesn't stop the next one. Getting the allergy under control usually does.

We check ears at every wellness visit, not just when something looks wrong, because early buildup is a lot easier to treat than a full infection. If your pet has been through multiple rounds of ear medication, the next conversation worth having is about what's actually causing it.

A pet that's constantly itching is uncomfortable. If you've been dealing with scratching, licking, or recurring infections for more than a few weeks, a proper diagnosis is the next step.
