Why Do I Itch When My Dog Touches Me? Facts to Know

Dogs are known for their loyal companionship and affectionate nature. However, for some individuals, being in close contact with their furry friends can lead to an annoying and uncomfortable sensation—itchiness. 

If you find yourself scratching incessantly when your dog touches you, you may be experiencing an allergic reaction or sensitivity. In this article, we will explore the reasons behind this phenomenon and delve into the world of canine allergies and sensitivities.

Understanding Allergies and Sensitivities

What Are Allergies? 

Allergies are a result of the immune system’s overreaction to substances that are typically harmless. 

When an allergic individual comes into contact with an allergen, such as pollen or pet dander, the immune system mistakenly identifies it as a threat and releases chemicals, such as histamine, to fight off the perceived invader. 

These chemicals trigger various symptoms, including itching, redness, sneezing, and congestion.

Differentiating Allergies from Sensitivities 

Allergies and sensitivities share similarities, but they have distinct differences. Allergies involve an immune response, while sensitivities refer to a non-immunological reaction to a substance. 

While allergies often result in immediate and intense symptoms, sensitivities may cause delayed and milder reactions. Both allergies and sensitivities can manifest in various ways, including itching, rashes, or respiratory issues.

Canine Allergies and Sensitivities

Can Dogs Cause Allergic Reactions? 

Yes, dogs can trigger allergies in susceptible individuals. The primary allergen associated with dogs is a protein found in their skin cells, urine, and saliva called Canis familiaris allergen 1 (Can f 1).

When a person with dog allergies comes into contact with these allergens, their immune system reacts, leading to symptoms such as itching, sneezing, wheezing, and hives. 

It’s essential to note that dog breeds with minimal shedding, like poodles or bichon frises, are often considered hypoallergenic, but no dog breed is entirely hypoallergenic.

What About Sensitivities? 

Apart from allergies, some individuals may experience sensitivities to dogs. These sensitivities can be caused by a range of factors, such as the dog’s grooming products, saliva, or even the environment in which the dog lives. 

Sensitivities can result in similar symptoms to allergies, including itching and skin irritation. Identifying the specific trigger can help manage and alleviate the discomfort.

Managing and Reducing Itchiness

Minimizing Exposure: If you’re experiencing itching when your dog touches you, taking steps to reduce your exposure to allergens or sensitivities can be beneficial. 

Consider creating designated pet-free zones in your home, investing in an air purifier, or using hypoallergenic bedding to minimize exposure to allergens. 

Regularly bathing your dog using gentle, hypoallergenic shampoos can also help reduce allergen levels on their skin and coat.

Medications and Treatments: In cases of severe allergies or sensitivities, over-the-counter or prescription medications may be necessary. Antihistamines can help relieve itching and other symptoms by blocking the effects of histamine. 

Nasal sprays and eye drops may also provide relief for respiratory or ocular symptoms. It’s crucial to consult with a healthcare professional to determine the most suitable treatment options for your specific condition.

Allergen Immunotherapy: For individuals with severe allergies, allergen immunotherapy, commonly known as allergy shots, may be recommended.

This treatment involves receiving gradually increasing doses of allergens over time to desensitize the immune system. Allergy shots can provide long-term relief and reduce the severity of symptoms.


Experiencing itchiness when your dog touches you can be frustrating, but it’s important to remember that you’re not alone. 

Allergies and sensitivities to dogs are relatively common, and understanding the underlying causes can help you manage the symptoms effectively. 

By minimizing exposure, considering medications or treatments, and exploring allergen immunotherapy, you can find relief and continue enjoying the companionship of your four-legged friend. 

If symptoms persist or worsen, consulting with a healthcare professional or allergist is recommended to receive appropriate guidance and support.
