Preventing and Treating Common Dog Allergies

Dogs are considered man’s best friend, but unfortunately, many people suffer from allergies to dogs. According to the American College of Allergy, Asthma, and Immunology, about 10% of the population is allergic to dogs. Dog allergies can cause symptoms such as sneezing, runny nose, itchy eyes, and even asthma attacks. However, there are steps you can take to prevent and treat common dog allergies. In this article, we will discuss some ways to prevent and treat dog allergies.

Understanding Dog Allergies

Dog allergies are caused by an overreaction of the immune system to dog dander, saliva, or urine. Understanding dog allergies is essential for pet owners who want to provide the best care for their dogs. Dogs can develop allergies to many different things, such as food, pollen, mold, and even human dander. Allergies can cause a variety of symptoms, including skin rashes, itching, sneezing, and even digestive problems.

Allergies in dogs are caused by an overactive immune system. When a dog is exposed to an allergen, their immune system releases histamines, which can cause inflammation and irritation. This is what causes the symptoms of allergies. The severity of the symptoms can vary depending on the dog and the allergen.

It is important to note that allergies are not the same as intolerance. A dog with a food intolerance may experience vomiting, diarrhea, or other digestive problems. While these symptoms can be uncomfortable for the dog, they are not caused by the immune system and are not considered an allergy.

Preventing Dog Allergies

While some dogs may be predisposed to allergies due to genetics, there are several steps you can take to reduce your dog’s risk of developing allergies. These include feeding your dog a high-quality, balanced diet, keeping your home clean and free of dust and allergens, and avoiding exposure to common allergens like pollen, mold, and dust mites. Regular grooming and bathing can also help keep your dog’s skin and coat healthy, reducing the risk of allergies and skin irritations.

Preventing dog allergies involves reducing your exposure to dog dander, saliva, and urine. Here are some ways to reduce your exposure:

  • Choose a hypoallergenic dog breed: Some dog breeds are less likely to cause allergies than others. Hypoallergenic dog breeds have hair instead of fur, which means they shed less dander.
  • Bathe your dog regularly: Regular baths can help reduce the amount of dander on your dog’s skin and fur. Use a mild dog shampoo and rinse your dog thoroughly to remove all the soap.
  • Keep your home clean: Vacuum your home regularly to remove dog dander from carpets and furniture. Use a vacuum cleaner with a HEPA filter to trap small particles of dander. Wash your dog’s bedding regularly in hot water to kill dust mites and other allergens.
  • Use an air purifier: An air purifier with a HEPA filter can help remove dog dander from the air in your home. Place the air purifier in the room where your dog spends most of its time.

Treating Dog Allergies

If you already have dog allergies, there are several ways to treat them. Here are some options:

  • Antihistamines: Antihistamines are medications that block histamine, which is released by the body in response to an allergic reaction. They can help relieve symptoms such as sneezing, runny nose, and itchy eyes. Some common antihistamines include loratadine, cetirizine, and fexofenadine.
  • Decongestants: Decongestants can help relieve nasal congestion caused by dog allergies. They work by shrinking the blood vessels in the nasal passages, which reduces swelling and congestion. Some common decongestants include pseudoephedrine and phenylephrine.
  • Nasal corticosteroids: Nasal corticosteroids are medications that reduce inflammation in the nasal passages. They can help relieve symptoms such as sneezing, runny nose, and congestion. Some common nasal corticosteroids include fluticasone, mometasone, and budesonide.
  • Immunotherapy: Immunotherapy, also known as allergy shots, can help reduce your sensitivity to dog allergens over time. It involves receiving regular injections of small amounts of dog allergens over a period of several years. This can help desensitize your immune system to dog allergens and reduce your allergic reaction.

Allergy Testing for Dogs

If you suspect that your dog is suffering from allergies, your veterinarian may recommend allergy testing to identify the allergens that are causing the reaction. There are two types of allergy tests available: skin testing and blood testing. Skin testing involves injecting small amounts of allergens under the skin to see which ones cause a reaction, while blood testing looks for antibodies in the blood that are produced in response to specific allergens.

Allergy Medications for Dogs

Depending on the severity of your dog’s allergies, your veterinarian may recommend medication to help control the symptoms. Some common medications used to treat allergies in dogs include antihistamines, corticosteroids, and immunosuppressive drugs. It’s important to follow your veterinarian’s instructions when administering these medications, as some can have side effects if given in the wrong dosage.

Natural Remedies for Dog Allergies

If you prefer to take a more holistic approach to treating your dog’s allergies, there are several natural remedies that may be effective. These include probiotics, omega-3 fatty acids, and herbal supplements like chamomile and nettle. However, it’s important to talk to your veterinarian before giving your dog any natural remedies, as some can interact with medications or cause unwanted side effects.


Dog allergies can be a frustrating and uncomfortable problem for many people. However, by taking steps to prevent and treat dog allergies, you can enjoy the companionship of your furry friend without suffering from allergic symptoms. If you suspect that you have dog allergies, talk to your doctor about your symptoms and possible treatments.
