Did you know that dogs can get seasonal allergies just like humans? It's true! Seasonal allergies in dogs usually manifest as itchy skin, but there are other telltale reactions. For instance, if your pooch has a runny nose, is excessively scratching, or just acting a bit off, it could very well be allergies.
Here are some ways you can identify seasonal allergies in dogs, as well as tips for getting your pet back up and running should they fall under the weather.
Signs of Dog Seasonal Allergies
The reactions dogs have to allergens are slightly different from those of humans. Itchy skin and recurrent ear infections are the most common signs of seasonal allergies in dogs, but your pet may also experience red, swollen eyes, a clear, runny nose and fits of sneezing.
The itchiness your pet may experience can range from intense to mild, and is most likely to occur in the armpit, groin, muzzle or paw regions. Note: Dogs can scratch themselves raw. So if you notice them scratching, rubbing on carpet or furniture, chewing or licking themselves more than normal, it's worth taking them to see a veterinarian. This behavior can lead to painful infections — signs of which include unusual odor and discharge — that will require treatment.

What Causes Dog Seasonal Allergies?
Seasonal allergies in dogs occur when they inhale or come in contact with something that they're sensitive to. Going a little deeper: allergies happen when the immune system becomes less tolerant of an allergen. After that, any time the immune system encounters that allergen in the environment, it goes haywire with an inflammatory response that causes all or some of the reactions mentioned above.
Seasonal allergies are brought on by factors only present during specific times of the year, such as tree and grass pollen, dust and dust mites, mold and mold mites, flea bites and fresh grass in the fall or summer.
How Are Seasonal Allergies in Dogs Diagnosed?
Your vet can tell you for sure if your dog is experiencing seasonal allergies or something else, based upon your pet's history, a physical exam, laboratory tests and their response to therapy. You can also take your dog to a dermatologist for skin testing — another accurate method for diagnosing seasonal allergies.
Skin testing is usually performed by a board-certified veterinary dermatologist, who measures your pet's reaction to microdoses of different allergens to determine exactly which they're allergic to. Using this information, they can make a serum for allergy shots that may make your dog's response to allergens less intense over time.
Blood testing is another route to consider, although skin testing is considered the more accurate approach.
