Allergies affect both dogs and their owners all year round. These allergies can be from a variety of things. Most people only expect seasonal allergies to occur in the Spring, but all seasons can come with their own set of environmental allergens.

What are Dog Allergies?

There is a wide range of types of allergies, all that may or may not affect your dog. Dog allergies themselves are a reaction to foreign substances by the dog’s immune system. These can come from reactions to foods, things on their skin, and environmental allergens. Fall allergies for dogs are not a complicated thing to deal with, and following these tips will help you and your get through it.

Food allergies

These allergies come from what your dog is eating. These food allergies have a wide range, the most common for a dog being beef, dairy and wheat. The least common dog food allergies are fish and rabbit. Some breeds of dog are more prone to having food allergies than others, including Boxers, German Shepherds, Retrievers, Dachshunds, and more. Food sensitivities can also show gastrointestinal signs like vomiting or diarrhea, as well as showing themselves as skin allergies.

Skin allergies

Skin allergies present themselves as itchy skin that your dog will be noticeably itching and scratching, even chewing. These skin allergies can show up anywhere on their body, even on their paws. Skin allergies frequently come as a result of food allergies, environmental allergens, or flea allergy dermatitis. Flea allergy dermatitis is an allergic reaction to fleas on the dog's skin, resulting in red, inflamed and itchy skin.

Acute allergic reactions

Acute allergic reactions occur when your dog comes into contact with something that it is severely allergic to. These allergic reactions, known as anaphylaxis, are very severe and lead to swelling of the airway, inability to breathe, and a sudden drop in blood pressure. This could result from things like a bee sting, or contact with an allergen your dog has a severe reaction to.

Environmental allergies

Environmental allergies come most often as a result of grasses pollinating. Different grasses pollinate at all different times of the year. The most common human environmental allergy is known as “hay fever,” and is a result of grasses pollinating. The most common of these grasses to pollinate that causes allergies is ragweed.

Grasses that pollinate in the Fall

Many grasses that pollinate in the Fall can be allergens for both pets and their owners. The most common grass to cause allergies is ragweed. Other grasses that pollinate in the Fall that can also cause allergies are sagebrush, Russian thistle, plantain, cocklebur and lamb’s-quarters. Of course, your pet might not only have allergic reactions to grasses pollinating in the Fall, but also to Trees pollinating in the Spring, or other grasses pollinating in the Summer.


The Fall season is an optimal time for mold to grow in your home. Mold will grow rapidly in cold, dark places, and molds can be allergens and toxins to your and your dog. To deal with this, you should make sure to fix any moisture leaking issues, and regularly clean your dog’s beds and towels. Wash things with a drop of bleach to be sure to kill any present mold.

Dust Mites

Dust mite issues can worsen in the Fall when you keep your windows closed and your house sealed. Make sure to frequently air out your house!

What are the symptoms of fall allergies for dogs?

There are many symptoms that could show up if your dog is experiencing any sort of allergies. Dogs typically do not show the same symptoms of an allergy that humans do, such as sneezing, but instead mostly scratch and lick or chew their skin. This response to allergies can cause hair loss, open sores, and secondary skin infections, so it is important to notice these signs as early as possible.

Itchy skin

Itchy skinis typically the first sign of an allergy noticed by owners, as their dog will be licking, chewing, or scratching one spot very often. This is caused by the pollen landing on their skin, and then their skin has an allergic reaction to pollen.

Itchy ears

Itchy ears is another very common symptom in dogs with allergies. Allergies can also show up in the ears of a dog through recurrent ear infections, even without other typical allergy symptoms. Many pet owners may not notice this and not realize that the source of recurrent ear infections is actually due to allergies.

Watery eyes

Your dog’s eyes may appear more watery than they usually are. The watery eyes may also come with your dog rubbing them, and your dog will just be visibly more uncomfortable regarding his or her eyes.

Excessive paw licking

Excessive paw licking is a typical telltale sign of your dog experiencing allergies. This means that your dog will be nearly constantly licking, or even chewing, their paws. This is a typical symptom of skin allergies, as your dog’s paws will be very itchy, tempting them to lick and chew.
