Pollen Allergy Symptoms in Dogs

Pollen allergies are among the most common allergies in dogs. The pollen allergy symptoms are similar to the symptoms of other allergies, so it is difficult to determine whether your pet is allergic to pollen. However, there are blood and skin tests that can indicate the particular irritant your dog is allergic to. Here's a look at the symptoms of pollen allergies in dogs:

Excessive Scratching

Pollens can cause allergic reactions in dogs that have a frail immune system. The pollens may be inhaled or may penetrate the skin of the dog. The skin can become irritated and itchy, and the dog will be scratching incessantly. If the allergies are not controlled, the scratching can cause wounds and bleeding, which will facilitate the occurrence of infections. Hair loss may also occur due to excessive scratching.


If the pollens are inhaled, these will most likely cause sneezing. The sneezing may be mild or more severe, depending on how allergic to dog is. The dog may also experience watery discharges from the nose.


If the pollen allergies are severe, coughing can also be a symptom. Coughing is caused by the irritation of the airways and lungs. The dog may also experience difficulty breathing. He may require immediate help if he gasps for air, as he may have anaphylactic shock, which is a severe allergic reaction causing swelling of the air passages.

Irritated Skin

The skin will be irritated due to the excessive scratching, but there may also be distinctive rashes, which may not be noticeable due to the hair. If you take a closer look you may observe these rashes. There may also be small bumps or the skin can become dry and flaky.

Licking or Biting of Paws

Pollen allergies may cause itchy paws, and the dog will lick and bite his paws while attempting to relieve the discomfort. Hair loss may be seen on the paws if the allergies are not detected.


The dog may be unusually aggressive, because he's not comfortable and he may scratch or even bite people that are familiar to him. The dog will not respond to commands and may also display an unusual behavior.


The dog can scratch and look agitated, but this may alternate with a state of lethargy. The dog will not be interested in normal activities and will prefer to sleep or hide. He may also lack appetite and avoid eating.

These symptoms are only present during pollen season and this is a way of detecting your pet is allergic to pollen. Other allergens will cause symptoms all year round. The symptoms will be more severe after the dog is exposed to pollens and after being outside. The dog may sneeze constantly while he's exposed to pollens. Note that pollens will be indoors as well, as they are airborne. However, the concentration of the pollen indoors is reduced.

If you find these symptoms in your dog you need to have some tests done. These will be conclusive in determining whether your dog is allergic to pollens or other substances.
