Summer has given way to fall, and winter is right around the corner. Unfortunately, these seasonal changes bring more than falling leaves and snow: they also cause many dogs to develop allergies. Seasonal allergies are amongst the most frustrating kinds of allergies for a pup and her parents to face. Whether it’s the incessant scratching at the ears, constant chewing on the paws, or frequent sneezes, dogs with seasonal allergies suffer all kinds of discomfort at this time of year. As a pet parent, you may feel helpless to make your pup feel better. We’re here to help with four tips to successfully treat seasonal allergies in your dog.

What causes seasonal allergies in dogs?

While many pup parents notice when their dogs start suffering from seasonal allergies, they may not know the source of the inflammation and reaction. An allergic reaction occurs in your dog when she is exposed to an environmental allergen and her immune system reacts in harmful ways. Generally, the immune system is there to protect your dog from disease and infection, but some environmental allergens cause the canine immune system to respond incorrectly.

When a canine sensitivity to an allergen occurs, the immune system overreacts by releasing too many histamines, a defense against any foreign proteins within the body. The result is often one or more of these symptoms: itching, swelling, and inflammation.

Here are some of the common environmental causes of seasonal allergies in dogs:

  • fungi
  • mold spores
  • weeds
  • grass
  • plant and tree pollens
  • dust
  • feathers

Dogs with seasonal allergies often suffer from one or more of these symptoms:

  • itchy, patchy, or flaky skin
  • hot spots
  • hair loss
  • open sores on the skin
  • runny nose
  • swelling
  • eye irritations
  • scabbing
  • sneezing
  • vomiting
  • smelly or dirty ears
  • respiratory congestion
  • diarrhea

In some cases, dogs with seasonal allergies may chew or scratch themselves so much that secondary ear and skin infections develop. The most commonly irritated areas include the head, ears, stomach, groin, armpits, and paws.

4 ways to treat seasonal allergies in dogs

Watching your dog suffer from allergies of any kind is difficult for a pup parent. Thankfully, there are some steps and remedies you can use to make your dog’s life less itchy and more comfortable.

1. Bathe the allergens away

Offer your pup some immediate relief by washing away the allergens on her body with regular baths. Use a gentle, hypoallergenic shampoo or one that is specifically formulated to soothe sensitive or inflamed skin. Products that include evening primrose oil, oatmeal, or aloe are ideal selections to help stop and prevent future allergic reactions.

2. Keep your pup’s favorite spots fresh and clean

Whether your dog sleeps in bed with you or has her own bed or blanket she lays down on, you want to wash all bedding in hot water at least once a week. Placing towels or covers on top of the bedding may act as an additional barrier between allergens and your dog’s body.

If your dog loves to lie on the chair, couch, or floor, keep these areas vacuumed and cleaned regularly with non-toxic house cleaners as much as possible.

3. Add some supplements to the mix

Research shows that some dogs may see a reduction in their seasonal allergies with the addition of supplements to their diet. From vitamin C to magnesium to curcumin to fish oil, there are a variety of anti-allergy supplements that may make a difference in your dog’s life.

Most supplements are available in various forms that are easy to add to your pup’s daily meals. For example, omega-3 fatty acid fish oil supplements come in soft gel and pill forms, both of which can be mixed into your dog’s food or masked with foods like peanut butter or pill pockets.

Always remember to speak with your veterinarian before giving your dog any new supplements.

4. Stop allergens before they get in the door

Pollen levels are often highest in the early morning and evening, so if you can avoid walking your dog during those times, you may be able to limit her exposure to these environmental triggers. Take the same approach with any parks or trails where your pup may come in contact with offending pollen, grass, or weed.

If changing where and when you walk your dog isn’t realistic, you can still stop allergens before they get into your home. After your walk, wipe your dog’s paws thoroughly with fragrance-free hypoallergenic wipes. You will immediately remove pollen or other allergens from your pup’s body without the need for a full bath. This step also stops the allergen from entering your home and potentially continuing to irritate your dog.

Other means by which to prevent your dog from walking in environmental allergens include dog boots and DIY methods, such as soaking your pup’s paws in apple cider vinegar to remove the pollen. For this DIY approach, mix 2 parts water to 1 part apple cider vinegar.

BONUS TIP – Adjust Your Daily Walk Routine

Did you know that pollen levels are highest in the early morning and late afternoon? For this reason, it’s best to avoid walking your dog at these times. You’ll also want to stay away from fields and  parks that may contain troublesome plants.

When you return home from your walks, be sure to wipe your dog’s paws and body with some pet-friendly wipes that are  hypoallergenic and fragrance-free. This will remove the allergens from your dog without the need to give them a full bath. Be sure to give those paws a good cleaning because the skin here is extra sensitive and often affected by allergens. Another solution (if your dog will tolerate it, and that’s a BIG if) – try putting booties on your dog when you walk her to keep her from stepping in anything that irritates her skin and tracking it into the house.

Take serious allergic reactions to the vet

If your dog’s seasonal allergies are interfering with her ability to have a good quality of life, make an appointment with your veterinarian as soon as you can. A professional can provide a better idea of the allergen’s source. Also, they can offer more aggressive options to tackle those allergies, including medications, steroids, antihistamines, and immunotherapy (allergy shots).

Serious allergies add up to serious veterinary bills, so make sure your dog has a pet insurance policy that can help you cover her care. Don’t have pet insurance? Get a free, personalized quote here.
