Your furry friend’s itchy skin might be more than just a nuisance. Allergic dermatitis is a common condition in dogs and can significantly impact their quality of life. Here’s what you need to know:

What is Allergic Dermatitis?

Allergic dermatitis is an inflammatory skin condition triggered by an allergic reaction to substances in the environment, food, or parasites like fleas. It leads to itching, redness, and even secondary infections if left untreated.

Types of Allergic Dermatitis:

Atopic Dermatitis: This is caused by environmental allergens like pollen, dust mites, and mold.
Food Allergy: Dogs can develop allergies to certain ingredients in their food, typically the protein, leading to skin irritation.
Flea Allergy Dermatitis (FAD): Some dogs are hypersensitive to flea saliva, causing severe itching and inflammation even with just a few flea bites.

Clinical Signs:

Itching (scratching, licking, chewing)
Red, inflamed skin
Hair loss
Skin infections (due to itching)
Recurring ear infections (common in allergic dogs)

Diagnosis:

Your veterinarian will conduct a thorough physical examination and may recommend additional tests such as

Skin scrapings/cytology: used to microscopically identify type of infection or parasite that is affecting your pet
Food elimination trial: your pet is fed a limited antigen diet exclusively for up to 8 weeks, then challenged
Serum Allergy Testing: blood test that can be used to identify allergens and develop immunotherapy injections based on results

Treatment:

Medications: Antihistamines, steroids, or immunosuppressive/modulating drugs may be prescribed to manage itching and inflammation.
Topical Therapy: Shampoos, sprays, and ointments can soothe the skin and reduce irritation.
Allergen Avoidance: If the allergen is identified, minimizing exposure can help manage symptoms.
Flea Control: Strict flea control measures are essential for dogs with flea allergy dermatitis. Year-round flea and tick prevention is recommended for every pet, but especially if they have flea allergies.
Your veterinarian may recommend referral to a board-certified veterinary dermatologist depending on chronicity and severity of clinical signs

Prevention:

Regular grooming and bathing can help remove allergens from your dog’s coat.
Maintain a clean living environment by vacuuming frequently and washing bedding regularly.
Feed a balanced diet and avoid known allergens if your dog has food allergies.

Allergic dermatitis can be frustrating for both you and your furry companion, but with proper management and communication with your veterinarian, it can be controlled effectively. If you notice any signs of skin irritation or itching in your dog, don’t hesitate to seek veterinary advice.
