How To Tell If Your Dog Has Allergies & What To Do

Dogs can suffer from allergies year-round, whether from seasonal pollen, food sensitivities, or environmental factors like dust mites and household irritants. Just like humans, dogs can be sensitive to pollen, mold, dust mites, and other environmental triggers. If your pup suffers from allergies, recognizing the symptoms and knowing how to manage them can improve their quality of life. Here’s everything you need to know about identifying and treating allergies in dogs, including seasonal, food, and environmental triggers.

1. Signs Your Dog Has Allergies

Dogs with allergies often show symptoms that affect their skin, respiratory system, or digestion. These symptoms can occur due to seasonal allergens, food sensitivities, or environmental triggers.

Common signs include:

• Excessive scratching, licking, or chewing (especially on paws and ears)

• Red, inflamed skin or hot spots

• Watery, itchy eyes

• Sneezing or coughing

• Ear infections or excessive ear wax buildup

• Runny nose

• Hair loss or bald patches

• Frequent paw chewing or face rubbing

• Digestive issues such as loose stools or vomiting (less common)

If you notice any of these symptoms, your dog may be suffering from seasonal allergies.

2. Common Causes of Allergies in Dogs

Dogs can suffer from various types of allergies, including seasonal, food, and environmental allergies.

Common causes include:

• Pollen (from trees, grass, and weeds) – More common in spring and fall.

• Mold spores – Thrive in damp environments and can be a year-round issue.

• Dust mites – Found indoors, especially in bedding, carpets, and upholstery.

• Flea bites – Some dogs develop flea allergy dermatitis (FAD), making flea prevention essential.

• Household irritants – Perfumes, cleaning products, and cigarette smoke can trigger allergies.

3. Managing Your Dog’s Allergies

Once you’ve identified your dog’s allergy triggers, the next step is managing them effectively. From environmental changes to diet modifications and medical treatments, these strategies will help your pup feel better year-round.

🌿 Reduce Allergen Exposure

• Wipe down your dog’s coat and paws after walks to remove pollen.

• Bathe your dog regularly using a gentle, hypoallergenic shampoo.

• Wash bedding frequently to reduce dust mites and allergens.

• Use air purifiers to filter out pollen, dust, and mold spores.

• Keep windows closed during high pollen seasons.

💊 Medications & Supplements

• Antihistamines (like Benadryl or Zyrtec) – Always consult your vet for proper dosage.

• Omega-3 fatty acids – Help reduce inflammation and promote healthy skin.

• Prescription allergy medications – If symptoms are severe, your vet may prescribe stronger treatments.

• Probiotics – Support gut health and may help improve immune response to allergens.

🍖 Dietary Changes

• Switch to a limited-ingredient diet if food sensitivities are suspected.

• Incorporate anti-inflammatory foods like salmon, coconut oil, and turmeric.

• Use fresh or homemade meals that avoid processed fillers and allergens.

🐾 Flea & Tick Prevention

• Use flea preventatives to avoid allergic reactions to flea bites.

• Vacuum frequently to remove flea eggs and dust mites from carpets and furniture.

4. Home Remedies for Treating Allergies at Home

In addition to vet-recommended treatments, there are several natural remedies you can try at home to ease your dog’s allergy symptoms.

While veterinary care is crucial for severe allergies, there are several home remedies that can help alleviate mild to moderate symptoms:

🌿 Natural Topical Treatments

• Oatmeal Baths – Soothing for itchy skin, an oatmeal soak can reduce inflammation and relieve discomfort.

• Apple Cider Vinegar (Diluted 50/50 with Water) – Acts as a natural antifungal and antibacterial rinse for paws and skin irritations.

• Coconut Oil – A natural moisturizer that can help with dry, itchy skin and provide anti-inflammatory benefits.

🍵 Homemade Allergy Relief Sprays

• Chamomile or Green Tea Rinse – Brew and cool tea, then apply it as a rinse to soothe irritated skin.

• Aloe Vera Gel (Pure and Unscented) – Can be applied to hot spots or inflamed skin for cooling relief.

🥗 Dietary Support for Allergies

• Raw Honey – A small amount of local raw honey may help build immunity to pollen allergies over time.

• Quercetin (Natural Antihistamine from Fruits & Veggies) – Found in apples, blueberries, and kale, quercetin helps reduce histamine reactions.

• Bone Broth – Provides gut health support, which is essential for allergy management.

💨 Environmental Adjustments

• Regularly washing your dog’s paws after walks to remove allergens.

• Using a HEPA air purifier to reduce indoor allergens.

• Frequent vacuuming and cleaning bedding to minimize dust mites and allergens.

These natural remedies can be great complementary approaches to veterinary treatments and preventative care.

5. Complications That Can Arise from Allergies

If allergies are left untreated or poorly managed, they can lead to more serious health concerns. Some common complications include:

• Yeast Infections – Constant licking and scratching can create a moist environment where yeast thrives, leading to infections, particularly in the ears and paws.

• Bacterial Skin Infections (Pyoderma) – Persistent scratching and open sores can allow bacteria to enter the skin, causing infections that require antibiotics.

• Ear Infections – Allergies can lead to excessive ear wax buildup and inflammation, making the ears more susceptible to infections.

• Chronic Hot Spots – Red, inflamed, and painful skin lesions that worsen with licking and scratching.

• Respiratory Issues – In severe cases, allergies can cause wheezing or difficulty breathing, especially in brachycephalic (short-nosed) breeds.

• Gastrointestinal Issues – Some food allergies can result in chronic diarrhea, vomiting, and overall digestive discomfort.

By addressing allergies early and implementing effective management strategies, you can prevent these complications and keep your dog comfortable and healthy.

6. When to Seek Veterinary Care

If your dog’s symptoms persist despite at-home treatments, or if they develop severe reactions such as difficulty breathing or open sores from excessive scratching, consult your veterinarian. They may recommend:

• Allergy testing to identify specific triggers.

• Steroid or immunotherapy treatments for severe cases.

• Medicated shampoos or topical treatments for skin relief.
