Autumn Allergies in Pets: Symptoms and How to Help Your Pet Feel Better

As the seasons change, so do potential allergens in the environment. While many pet owners associate allergies with spring, autumn allergies can be just as troublesome for dogs and cats. As trees shed their leaves, mould spores increase, and dust mites become more active indoors, many pets experience uncomfortable allergy symptoms.

Common Symptoms of Allergies in Pets

Just like humans, pets can develop seasonal allergies that flare up during autumn. The most common symptoms include:

• Excessive itching and scratching
  
• Red, inflamed, or irritated skin
  
• Frequent ear infections or head shaking
  
• Watery eyes and nasal discharge
  
• Licking or chewing paws
  
• Sneezing and coughing

These symptoms can make your pet miserable, but with the right approach, you can help them find relief.

Causes of Seasonal Allergies in Pets

Unlike spring allergies, which are often triggered by pollen, autumn allergies tend to be caused by:

• Mould spores: Fallen leaves, damp soil, and decaying plants create the perfect environment for mould, which can trigger allergic reactions in pets.
  
• Dust mites: As temperatures cool, pets spend more time indoors, where dust mites thrive in carpets, bedding, and furniture.
  
• Weed pollen: While tree and grass pollen levels drop, certain weeds (like ragweed) release pollen in autumn, affecting sensitive pets.

​Unlike food allergies, which result from dietary sensitivities, pet allergies are typically inhaled or absorbed through the skin, leading to a range of uncomfortable symptoms.

Treatment Options for Autumn Allergies in Pets

Wondering how to treat pet allergies? Managing your pet’s allergies requires a combination of symptom relief and long-term treatment strategies. Depending on the severity of your pet’s allergies, your veterinarian may recommend one or more of the following treatments:

1. Antihistamines
Over-the-counter or prescription antihistamines, such as cetirizine or loratadine, can help reduce itching and inflammation. However, not all pets respond the same way, so it’s important to consult your vet for the right dosage and medication.

2. Medicated Shampoos and Topical Treatments
Frequent baths with hypoallergenic or medicated shampoos can soothe irritated skin and wash away allergens trapped in the fur. Topical sprays, creams, or wipes containing anti-inflammatory ingredients may also provide relief for itchy, red skin.

3. Prescription Allergy Medications
​
For pets with severe allergies, veterinarians may prescribe stronger treatments, such as:

• Corticosteroids: Effective for reducing inflammation but should only be used under veterinary supervision due to potential side effects.
• Apoquel: A medication that targets the specific pathway responsible for itching in allergic reactions.
• Cytopoint: An injectable treatment that blocks itch signals and provides relief for several weeks.

4. Immunotherapy (Allergy Shots)
If allergy testing identifies specific triggers, allergy shots (also known as immunotherapy) can help desensitise your pet’s immune system. This long-term treatment gradually builds tolerance to allergens, reducing symptoms over time.

5. Dietary Supplements for Skin Health
Adding Omega-3 fatty acids to your pet’s diet can strengthen the skin barrier and reduce inflammation. Probiotics may also support immune function and help manage allergic reactions.

How to Help Your Pet Feel Better

If your pet is showing signs of allergies, there are several ways to manage their discomfort:

1. Keep Your Home Allergen-Free

• Regularly vacuum carpets and furniture to reduce pollen and dust buildup.
• Use air purifiers to filter airborne allergens.
• Wash your pet’s bedding frequently.

​2. Bathe Your Pet and Wipe Their Paws

• A gentle, hypoallergenic shampoo can soothe irritated skin and remove allergens from fur.
• Wiping your pet’s paws after outdoor walks can prevent them from bringing allergens inside.

3. Consult Your Veterinarian

• A vet can determine if allergy medications, such as antihistamines or corticosteroids, are needed.
• Prescription treatments, like allergy shots or medicated shampoos, may provide long-term relief.
• For severe cases, allergy testing can identify specific triggers.

4. Provide a Balanced Diet with Supplements

• Omega-3 fatty acids help strengthen skin barriers and reduce inflammation.
• Some pets benefit from probiotics, which support immune health.

Allergy Testing: Identifying the Cause of Your Pet’s Discomfort

If your pet suffers from persistent allergy symptoms, allergy testing can help pinpoint the specific triggers. There are two main types of allergy testing for pets:

1. Intradermal Skin Testing
This is considered the gold standard for diagnosing environmental allergies. A veterinarian or veterinary dermatologist injects small amounts of common allergens under the skin and observes the reaction. If a raised, red bump appears at the injection site, it indicates an allergic response to that specific allergen. This test is commonly used for seasonal allergies triggered by pollen, dust mites, or mould.

2. Blood Testing (Serum Allergy Test)
A blood test measures the level of antibodies your pet’s immune system produces in response to different allergens. While not as precise as intradermal skin testing, it is a less invasive option that can still provide useful insights into potential allergens affecting your pet.

What Happens After Allergy Testing?

Once the specific allergens are identified, your veterinarian can develop a targeted treatment plan. This may include:

• Allergen avoidance – Reducing exposure to the identified allergens where possible.
  
• Allergy shots (immunotherapy) – Gradual exposure to allergens through injections to build tolerance.
  
• Medications – Antihistamines, steroids, or other treatments to manage symptoms.

If your pet struggles with ongoing allergy symptoms, allergy testing can be a valuable step in creating a long-term relief strategy.

When to Seek Veterinary Care

If your pet's allergy symptoms persist or worsen, it's essential to visit your veterinarian for allergy treatments. Chronic itching, persistent ear infections, or severe skin irritation can lead to secondary infections, which require medical attention.
