Feline Friends or Foes? Can Cats Be Allergic to Dogs?

Cats are notorious for their allergies, but did you know that they can also be allergic to dogs? As unexpected as it may sound, it is true.

Intradermal allergy testing has revealed that feline allergic reactions can also stem from dog epithelia. In this article, we will explore the possibility of cats being allergic to dogs and discuss the various ways to manage these allergies.

We will also provide you with tips and tricks to keep your allergic cat happy and healthy. Can Cats Be Allergic to Dogs?

Intradermal allergy testing in cats has revealed that feline allergies can also be triggered by dog epithelia. This means that cats can be allergic to dogs just like they can be allergic to certain foods, pollen, and other allergens.

Researchers found that cats are most commonly allergic to the Fel d 1 protein found in dog saliva and skin cells. This protein can travel through the air and stick to surfaces, including the fur and skin of other animals.

Breed-related variability in dog allergens is also a factor to consider. Studies have shown that different dog breeds produce different levels of Fel d 1.

For example, breeds like Poodles and Bichon Frises produce very little of the protein, making them a good choice for cat owners who are allergic to dogs. On the other hand, breeds like Bulldogs and Retrievers produce high levels of Fel d 1, making them more likely to cause an allergic reaction in cats.

Managing Allergies in Cats and Treatment Options

If you suspect that your cat is allergic to dogs, you can manage their allergies by minimizing their exposure to dog epithelia. This can be done by keeping your cat indoors, cleaning and vacuuming regularly, washing your dog regularly, and avoiding contact with other dogs.

You can also consult with your veterinarian about immunotherapy, also known as allergy vaccine, which can help train your cat’s immune system to tolerate allergens over time. Immunotherapy involves injecting your cat with small amounts of the allergen over a period of time to help their body build up a tolerance to it.

This treatment can take several months to years to complete, but it has shown to be effective in reducing allergic reactions in cats. Other treatments for feline allergies include antihistamines, corticosteroids, and allergy shots.

Keeping Your Allergic Cat Happy and Healthy

Prevention and management are key when it comes to keeping your allergic cat happy and healthy. Environmental and genetic factors play a significant role in feline allergies, so it is important to keep your cat’s environment clean and free of potential allergens.

This includes using hypoallergenic cat litter, avoiding scented cleaning products and air fresheners, and providing your cat with a healthy diet that includes omega-3 fatty acids. Omega-3 fatty acids have been shown to improve skin health in cats, which can help reduce allergic reactions.

You can add omega-3 fatty acids to your cat’s diet by including foods like salmon, sardines, and flaxseed, or by using supplements designed for cats.


Cats can be allergic to dogs, but with proper management and treatment options, you can still provide your feline friend with a happy and healthy lifestyle. Minimizing exposure to dog epithelia, consulting with a veterinarian about immunotherapy, and providing your cat with a clean and healthy environment can all help reduce allergic reactions.

Adding omega-3 fatty acids to your cat’s diet is also a great way to improve their overall skin health and reduce allergic reactions. With these tips and tricks, you can keep your allergic cat happy and healthy for years to come.Cats are known to have allergies to various substances, and determining if your feline friend is allergic to dogs can be a challenging task.

In this article, we will explore the clinical signs of allergies in cats, the skin infections caused by allergies, and the diagnostic testing available for pet allergies. We hope to provide you with valuable information to help you identify and manage your cat’s allergies.

Clinical Signs of Allergies in Cats

Clinical signs of allergies in cats can vary, but the most common symptom is itching or scratching due to skin irritation. Your cat may scratch excessively or lick its skin until it becomes raw, which can lead to open wounds and infections.

Other symptoms include sneezing, vomiting, diarrhea, and respiratory issues. If you suspect that your cat is allergic to dogs, it is essential to pay close attention to these symptoms.

It is important to note that symptoms alone are not enough to diagnose an allergy. A proper diagnosis requires an evaluation by a veterinarian, who can perform tests and examine your cat’s physical condition.

Skin Infections Caused by Allergies

Skin infections are one of the most common problems associated with allergies in cats, often due to the excessive scratching and biting of the skin. Allergies can cause the skin to become crusty, scaly, and inflamed, leading to the formation of hot spots or moist dermatitis.

Bacterial or fungal infections can also develop on broken skin, sometimes leading to systemic infections. It is crucial to watch for signs of skin infections on your cat, such as red, swollen, and oozing lesions.

If you notice these symptoms, it is essential to take your cat to the veterinarian promptly for diagnosis and treatment.

Diagnostic Testing for Pet Allergies

If you suspect that your cat is allergic to dogs, consult with your veterinarian. They can evaluate your cat’s symptoms and perform diagnostic testing to confirm if your cat is indeed allergic to dogs or any other allergen.

Blood testing is one of the diagnostic tests available for pet allergies, measuring your cats blood for the presence of specific antibodies. Skin testing is another option, which is considered the gold standard for diagnosing allergies in cats.

It involves injecting small amounts of suspected allergens just below the skins surface and monitoring the cat’s reactions. In addition to these allergy tests, your vet can also perform a skin biopsy to aid in diagnosis.

Diagnostic testing is crucial to determine what your cat is allergic to, as well as developing an appropriate management plan. It is essential to note that there is no cure for allergies in cats, and the best course of action is to prevent exposure to allergens as much as possible.

This includes avoiding contact between your allergic cat and other pets, including dogs, and keeping your cat in a clean and allergen-free environment.


Identifying allergies in your cat can be challenging, but paying close attention to clinical signs and symptoms can help diagnose the root cause of the problem. Skin infections due to allergies are also common in cats and need early intervention to prevent further complications.

Diagnostic testing is available to help pinpoint the cause of allergies, and developing an appropriate management plan is key to alleviating symptoms and preventing future allergic reactions. By understanding the clinical signs, skin infections, and diagnostic testing for pet allergies, you can be better prepared to identify, diagnose, and manage your cat’s allergies, which will lead to a happier and healthier pet.

In conclusion, identifying if your cat is allergic to dogs requires close observation of clinical signs such as itching and scratching. Skin infections caused by allergies are common in cats, and diagnostic tests such as blood tests and skin testing can help pinpoint the cause of allergies.

Managing allergies is crucial to prevent future allergic reactions and alleviate symptoms. Prevention and management strategies include minimizing exposure to allergens, such as avoiding contact with other pets, keeping the cat in an allergen-free environment, and providing a healthy diet.

By understanding the importance of diagnosing and managing allergies in cats, pet owners can ensure a healthier and happier life for their feline companions.
