Understanding Pet Allergies: Common Causes and Treatments for Dogs and Cats

05 Nov 2024
At My Pet World, we’re dedicated to educating pet parents on essential health topics, and allergies in pets are among the most common issues we see. Here’s an overview of the types of allergies affecting dogs and cats, symptoms to look out for, and the best ways to manage them, as shared by Dr. Randa at our October Meetup.

Types of Pet Allergies
Allergies, also known as hypersensitivities, can cause significant discomfort for dogs and cats, often leading to itchy skin, infections, and behavioral changes. The most common allergies are:
Food Allergy
  1. Unlike sensitivities to specific brands, food allergies stem from specific ingredients, which may trigger a reaction even in tiny amounts. These allergens are ingested and then processed by the immune system, which responds to these molecules, leading to skin itchiness, especially around the ears, and increased risk of infections.
  2. Diagnosis and Treatment: Food allergies can be identified through an elimination diet, a process where a special diet is followed for about eight weeks to identify the problematic ingredient. Additionally, flavored medications, such as heartworm pills, may need to be replaced temporarily with non-flavored options.
  3. Atopic Dermatitis (Environmental Allergies)
    This allergy is triggered by environmental factors like pollen, dust mites, or mold, leading to redness and itchiness in the skin and ears, which can further result in infections.
  4. Treatment Options: Managing atopic dermatitis usually requires trial and error. Options include topical treatments to remove allergens, as well as medications like antihistamines and corticosteroids to reduce inflammation. Consistent treatment is essential, as environmental allergies can flare up periodically.
  5. Flea Bite Allergy Dermatitis (FAD)
    Fleas are one of the most common external parasites in pets, and their bites can cause severe allergic reactions in some animals, leading to symptoms like red, inflamed skin, patches of missing fur, and the formation of painful “hot spots.”
  6. Treatment: Treating flea bite allergies involves a combination of approaches: topical therapies, steroids to alleviate itching, and antibiotics if infections are present. It’s essential to also keep the home environment clean and to implement regular flea treatments.
  7. Contact Allergy
    Contact dermatitis occurs when pets come into direct contact with specific allergens, often affecting the belly, muzzle, paws, and other areas that touch surfaces. Common allergens include plants, fabrics, and chemicals.
  8. Management: The best treatment for contact allergies is avoiding the allergen. In addition, topical treatments like medicated shampoos and ointments help soothe the skin and reduce inflammation.

Why Do Pet Allergies Affect the Skin?
One common question pet owners have is why ingested or inhaled allergens cause skin reactions. The answer lies in the skin's role as a defense barrier. The skin has numerous immune cells that produce antibodies (specifically IgE) that are involved in allergic reactions. When allergens reach these cells, they release chemicals that cause allergy symptoms, including itching and redness.

How My Pet World Supports the Pet Parent Community
