Dog Allergies in Winter

August 20, 2022by DOGuide0

Dogs can have allergies in any season, but dog allergies in winter can present like other conditions, such as the flu. That’s why it’s important to know as a dog owner whether your dog is suffering from seasonal allergies in the winter months or something much more serious.

How Common Are Dog Allergies in Winter?

While most people believe that seasonal allergies are for the spring and summer, dog allergies in winter are just as common.

Knowing the unique allergy symptoms for the winter months can help you identify what is causing them so you can provide some relief to your dog.

Symptoms of Dog Allergies in Winter

The symptoms of dog allergies in winter are similar to those in the spring and summer. The symptoms are caused by many different types of allergens and what your dog is allergic to. The most common dog allergies symptoms are:

  • Coughing
  • Runny Nose
  • Watery Eyes
  • Itchy Skin
  • Dry Skin
  • Sneezing

Due to the dry, cold weather, many of the symptoms have to do with a dog’s skin. With dry air and much less circulation indoors, allergies are much more common for some dogs.


What Causes Winter Allergies

Winter allergies can be caused by allergens inside and outside of the home. Below you will learn about allergy triggers in both environments.

Outdoor Allergies

The cold air outside is enough to make most people and animals suffer from dry skin. For dogs with sensitive skin, it can be quite painful. The winter air can cause a dog’s skin to itch, which then leads to scratching, which then leads to wounds on the skin.

Indoor Allergies

Since dogs spend more time indoors during the winter season, it makes sense that a lot of the allergies they suffer from have to do with allergens inside the house.

Dust Mites

Dust mites are tiny bugs that live in dust inside the home. People and animals who are not allergic to dust mites don’t even know they exist. Those allergic to dust mites will definitely know because it can cause sneezing and a runny nose.

Pet Dander

While many people are allergic to pet dander, many dogs are too. Unfortunately, since it’s on their own body, it can be difficult to get away from it.

Pet dander can increase in the winter because of the dry air leading to dry skin. The dry skin leads to itchy skin that becomes irritated to the point of wounds for some dogs. It’s especially severe when a dog suffers from dry skin during the spring and summer months.

Mold Spores

Another common indoor allergy is mold spores. These spores are invisible and float through the air. They come from mold, which occurs when surfaces are wet or damp.

Mold spores are common in homes that have suffered a water leak or flood.

Food Allergies

If you’re feeding a fresh raw dog food diet and make changes to it during the winter, your dog may suffer from an allergic reaction to it. So, while food allergies can happen at any time, the winter may spark some dog owners to offer more comfort food that may not be an allergy trigger for their pup.


How to Treat Dog Allergies in Winter

Winter allergies aren’t fun. Indoor allergies aren’t fun either. Cold weather can’t be stopped though, so all we can do is prevent allergic reactions to it. The following tips can help you treat and prevent dog allergies in winter.

Moisturizing Shampoo

Shampoo with extra moisturizer can greatly help with dry skin. It can also help with animal dander since it increases skin dryness in the winter season.

Regular Grooming

If your pup is suffering and you’re not able to treat the winter allergy symptoms easily, it may be time for medications. If you don’t want to take your pup to the veterinarian’s office, you can always use an online vet for prescription medication.

Switch to a Fresh Raw Food Diet

Dogs with food allergies may do better on a healthier diet – fresh raw dog food. Providing this type of diet to your dog can also boost the immune system, which can then help prevent many types of allergies, such as skin allergies, throughout the year.


Dog Allergies in Winter

Now you know that it is possible for dogs to suffer from allergies in the winter. The most common dog allergy in winter is itchy, dry skin due to the dry winter air. Other types of allergies have to do with dander, mold, and food.

The first step in helping your pup is identifying what is causing the allergic reaction. The second step is to avoid the allergen. If it can’t be avoided, treating the allergy symptoms is the logical next option.

Of course, if you’re not sure what is causing your dog’s allergies in winter, consult with your vet. Allergy testing can help identify what may cause the allergy symptoms so you can start working on a treatment.
