Is your dog’s constant scratching, itching, and sneezing making you both feel stressed? Just like humans, our canine companions can suffer from bothersome seasonal allergies, too.

For pet parents, it can be tough to see your furry friend in such obvious discomfort without knowing how to help. As a veterinarian with BetterVet, I examine many dogs with seasonal allergies.

Key Takeaways

In this blog post, I’ll explore dog seasonal allergy symptoms and go over some effective treatments to ensure your pup isn’t just surviving, but thriving, all year round.

What are Seasonal Dog Allergies?

Seasonal allergies in dogs, also known as atopy or canine allergic dermatitis, is a common health issue for many of our furry friends. Allergies develop when a dog’s immune system overreacts to environmental allergens such as pollens, molds, dust mites, and even certain insects.

To determine if your dog has seasonal allergies, a veterinarian will typically perform an allergy and dermatologic examination.

Signs Your Dog Has Seasonal Allergies

Dogs with seasonal allergies can exhibit a range of symptoms, primarily manifesting on the skin, but other areas can also be affected.

Here are the most common signs of seasonal allergies in dogs:

• Sneezing: Caused by their immune system reacting to airborne allergens like pollen, leading to inflammation in the nasal passages and attempts to expel these irritants.

• Excessive Scratching, Chewing, and Licking: One of the most noticeable symptoms is persistent scratching or licking. Dogs might chew or lick their paws, flanks, groin, or other areas of the body excessively.

• Skin Irritation: Affected dogs may develop redness, bumps, and inflammation on the skin. Areas that see a lot of friction, like the armpits, belly, and between the toes, are often the most affected.

• Ear Infections: Dogs with allergies may be prone to recurring ear infections which cause head- shaking, scratching at the ears, or even an unpleasant odor.

• Hot Spots: Allergies can lead to the development of hot spots, which are red, swollen, and painful areas of skin that can develop rapidly and can lead to hair loss.

• Changes in the Skin and Coat: Chronic itching and scratching can lead to changes in the skin’s color and texture. The skin may become thickened, darker, or take on a leathery texture. Hair loss or changes in coat quality may also be seen.

• Watery Eyes or Runny Nose: While less common, some dogs may also display symptoms similar to human symptoms of hay fever, such as watery eyes, runny nose, and even sneezing.

How to Treat Dog Seasonal Allergies

Seasonal allergies in dogs are typically managed rather than completely cured. Each dog will respond differently to treatments, so a multi-pronged approach is often the best course of action.

It’s always a good idea to consult with a veterinarian before starting any treatment regimen. They can help you come up with a personalized plan that best fits your dog’s needs.

Here are some vet-recommended steps to treat your dogs’ seasonal allergies:

Allergy and Dermatology Exam

The first step is always to consult with a vet. A comprehensive allergy and dermatology exam can help identify the allergens causing your dog’s symptoms and recommend specific treatments.

Antihistamines

Over-the-counter antihistamines such as Benadryl or Zyrtec might help alleviate some allergy symptoms. In more severe cases, your vet may prescribe prescription allergy medication like Apoquel, or steroids to reduce inflammation and itching. Always consult with your vet before giving your pet any medication.

Immunotherapy

If your veterinarian can identify the specific allergen affecting your dog, immunotherapy (allergy shots) can be an effective way to manage allergies. This involves giving the dog small amounts of the allergen to build up a tolerance over time.

Topical Treatments

Special shampoos, creams, and sprays can help soothe itchy, irritated skin. Look for products containing oatmeal, aloe, or hydrocortisone. Your veterinarian may also prescribe a medicated cream to use at home.

Home Remedies to Relieve Seasonal Allergies in Dogs

While home remedies can’t replace a pet wellness exam, they can sometimes provide additional relief for dogs with seasonal allergies. Remember, while home remedies can help manage symptoms, they’re not a substitute for veterinary treatment.

Here are some home remedies for managing your dogs’ seasonal allergies:

Omega-3 Fatty Acids

Omega-3 fatty acids can help decrease inflammation and are beneficial for skin health. They can be added to your dog’s diet as a supplement or by feeding foods rich in these fats.

Reduced Exposure to Allergens

Try to minimize your dog’s exposure to allergens. This might involve keeping windows closed during high pollen times, regularly cleaning your dog’s bedding, or wiping down your dog’s paws and coat after walks.

Flea Prevention 

Fleas can exacerbate allergies, so make sure your dog is on a good flea prevention program. Your veterinarian can recommend the right product and time for preventative treatments. 

Hypoallergenic Diet

Some dogs may benefit from a hypoallergenic diet, particularly if they have food allergies in addition to environmental allergies.

Oatmeal Baths

Oatmeal has natural anti-inflammatory properties and can be soothing for itchy, irritated skin. To give your dog an oatmeal bath, blend plain oatmeal into a fine powder, mix it with warm water, and let your dog soak in it for 10-15 minutes.

Coconut Oil

Coconut oil can be applied topically to help soothe your dog’s skin. You can also add a small amount to your dog’s diet (with vet approval) as it contains lauric acid which can help decrease yeast production, a common issue in dogs with allergies.

Aloe Vera

Aloe Vera gel can be applied to your dog’s skin to help soothe inflammation and itchiness. Make sure you’re using a pure product that’s safe for dogs and doesn’t contain alcohol.

Apple Cider Vinegar

You can use apple cider vinegar to make a spray for your dog’s skin. Mix equal parts vinegar and water and spray on your dog’s skin. Be careful not to spray on open wounds as it can sting.

Probiotics

Adding a canine probiotic supplement to your dog’s diet may help strengthen their immune system and potentially reduce allergic reactions.

Quercetin

This natural substance found in fruits and vegetables is often referred to as a natural antihistamine. Make sure to choose a supplement formulated specifically for dogs. 

Air Purifiers

To help reduce allergens in your home, consider using air purifiers. These devices can help remove allergens like pollen and dust from the air.
