Seasonal Allergies in Dogs

Sometimes, you might notice your dog’s allergies flare up at specific times of the year. These are seasonal allergies. 

Just like normal allergies, seasonal allergies happen when your dog’s immune system reacts to certain allergens. The main difference is that the symptoms only flare up when those specific allergens, like pollen or mold, are more concentrated in the environment.

Fortunately, this skin condition can be managed effectively. But first, our friends at Noble Vet Clinics will break down everything you need to know about seasonal allergies in dogs.

Main Causes of Seasonal Allergies in Dogs

Causes and triggers vary by location and season. Generally, these include:

• Mold Spores. Found in damp and moist environments, fallen leaves, and soil. Mold spores are common during the rainy and humid seasons.
• Dust and Dust Mites. Found in humid areas, especially during the summer months.
• Pollen. Found in trees, grass, and weeds. Tree pollen typically peaks in the spring, while grass and weed pollen are abundant from summer to fall.

Common Symptoms of Seasonal Allergies in Dogs

Because of the nature of the allergens involved, the signs of dog allergies are generally seen on the skin. These include:

• Excessive Scratching and Chewing. One of the most common symptoms of seasonal allergies in dogs is itching, which can occur on the paws, belly, face, and ears.
• Redness and Inflammation. Irritated, reddened skin often appears where your dog scratches the most. If left alone, these areas can also become swollen. 
• Ear Infections. Constant irritation and scratching often result in bacterial and fungal infections, with the ears being a common area affected.
• Hot Spots. If your dog’s scratching and licking becomes intense, hot spots are often the result. These are moist, oozing skin lesions that will need urgent vet care. 
• Skin Thickening. In long-term cases of scratching and irritation, the skin can thicken, a condition known as lichenification. 
• Behavioral Changes. When allergies flare up, affected dogs will be noticeably distraught, irritated, and uncomfortable. They may not want to engage in interactions or physical activity.

Diagnosing Seasonal Allergies in Dogs

The process can be tricky, as many conditions can irritate a dog’s skin. A dermatology exam is always the first step. Noble Vet Clinics’ experts will review your dog’s medical history, symptoms, and living situation.

Depending on the symptoms and observations, vets can proceed to allergy testing or other tests to rule out other conditions. These include:

• Intradermal Skin Testing. In this test, your dog will be sedated, and a small patch of fur will be shaved. Tiny amounts of common allergens will be injected just under the skin in a grid-like pattern. Any redness or symptoms will reveal a positive result of allergies.
• Serum Allergy Testing. Here, a blood test will be collected to check for IgE antibodies, which are produced as a response to allergens. The response will aid in determining the best treatment option.

• Flea Allergy Dermatitis. Diagnosed with a flea comb test, skin inspection, and flea control trial. 
• Food Allergies. Includes symptoms such as vomiting and diarrhea. This is generally diagnosed through an elimination diet. 
• Mange. Diagnosed through skin scrapings, acetate tape test, and anti-parasitic medications.
• Bacterial or Fungal Infections. Cytology and culture tests will provide accurate diagnoses.

Treatment for Dog Seasonal Allergies

After diagnosis, the next step is to manage your dog’s allergies. 

Medications such as antihistamines, corticosteroids, and oral tablets can help reduce itching, inflammation, and swelling. They work fast, but should not be used long-term. You can generally find these medications at vet clinics and pet pharmacies. 

Shampoos containing chlorhexidine or oatmeal can help relieve itching and calm inflamed skin. These are especially useful during allergy flare-ups to wash away allergens and reduce irritation.

Topical sprays and ointments can soothe hot spots and highly irritated areas, helping provide daily relief.

For long-term allergy control, allergen-specific immunotherapy can target the root cause. It works by gradually increasing the dog’s tolerance to the allergen, making them have milder reactions. This form of treatment generally takes a few months.

Supplements such as fish oil and probiotics are good allergy support for dogs. They can sustain your dog’s skin, immune system, and overall health. Because they’re natural, they’re generally safe to combine with medications.

Reducing your dog’s contact with allergens can make a big difference in easing symptoms and promoting recovery. Regular grooming and home cleaning can help keep seasonal allergens out of your dog’s living space.

Ways to Prevent Seasonal Allergies in Dogs

While you can’t change the seasons, there are ways you can reduce your dog’s exposure to these allergens. 

1. Adjust Outdoor Time

Dust can be more prevalent during the day, especially with more activity going on. Cars, people, and other pets can also carry allergens that might affect your dog.

2. Regularly Groom Your Dog

Keeping your dog clean stops allergens from accumulating on its body. Wipe down their paws and belly with a damp cloth after walks. Regular bathing with gentle, medicated shampoos can rinse away pollen and promote coat health. 

3. Clean Your Home

Aside from your dog’s hygiene, its environment should also be cleaned. Wash their bedding, toys, and blankets regularly.

Vacuum carpets and sofas that your dog frequently lies on.

4. Provide a Balanced Diet

Foods and supplements that support overall skin health are good additions to your dog’s diet. Be sure to ask your vet about your dog’s dietary needs. 

Conclusion

Seasonal allergies in dogs are more common than many pet owners realize, and they can seriously impact their comfort and happiness. But with the right approach and care, these can easily be managed.

It just takes a few steps to give your dog a happy and itch-free life.
