Dog Allergies – Causes, Symptoms And Treatment

Dog allergy is a nightmare for people, especially those who love to have a dog as a pet. Dog dander (dead skin flakes) is the chief cause of dog allergy in most people across the world. The most interesting fact about dog allergy is that people who have dogs are less likely to experience allergy symptoms than the ones who don’t own dogs.

This happens because dog releases a protein named endotoxin that boosts the human immune system to fight against allergies. Do not let dog allergy come between you and your dog. Here is a comprehensive way to tackle dog allergies.

Dog Allergy Causes

In contrast to the widely held beliefs, different dogs of the same breed release different allergens and can cause dog allergy. It is not necessary that only the long-haired or furry dogs cause dog allergies. In fact, the hair is not the underlying cause at all but the dog dander is. In addition, dog’s urine and saliva also cause dog allergies. Saliva of dogs contains the primary allergen namely Can f1.

In addition, a particular type of protein in dog’s blood called dog albumin causes dog allergies. Dog albumin reacts with albumin of other animals such as cats. Also, only those people with weak immune system are prone to dog allergy. In this case, their bodies mistake harmless substance in dog dander to be harmful virus or bacteria and react against it.

In an attempt to destroy this misunderstood allergen, the person experiences watery eyes and sneezing. Often people react to the pollen carried by the dog and mistake it for dog allergy.

Dog Allergy Symptoms

When people with dog allergy come in contact with dog dander they show symptoms such as wheezing, coughing, red and itchy eyes, sneezing, running nose, stuffy nose, etc. In some cases, people experience skin reactions when they come in contact with dogs.


Dogs show their affection by licking. In case of dog allergy, however, you might experience a break out in your skin right at the place where you were licked by the dog. In severe cases, dog allergies lead to hives on the person’s face and chest. The symptoms are always worse in case of people with asthma.
