Introduction:

Atopic dermatitis, also known as allergic dermatitis, is a common skin condition that affects many dogs. It can cause discomfort, itchy skin, and skin inflammation, significantly impacting their quality of life. In this blog post, we will explore the aetiology of atopic dermatitis in dogs, discuss preventive measures relevant to Brisbane, QLD, and highlight treatment options available at Newstead Vets to help manage this condition effectively.

Aetiology of Atopic Dermatitis:

Atopic dermatitis is primarily an allergic reaction triggered by exposure to certain allergens. The exact cause of this condition is multifactorial, involving a combination of genetic predisposition, environmental factors, and immune system dysregulation. Common allergens that can contribute to atopic dermatitis in dogs include:

1. Pollens: Brisbane, QLD, is known for its diverse plant life, which can lead to increased pollen levels. Dogs with atopic dermatitis may develop allergic reactions to specific pollens, such as grass, tree, or weed pollens.

2. Dust Mites: These microscopic creatures thrive in warm and humid environments, making Brisbane's climate ideal for their proliferation. Dust mites can trigger allergic reactions in dogs with atopic dermatitis.

3. Mould Spores: Brisbane's humid climate can also contribute to the growth of mould, leading to increased exposure to mould spores. Dogs with atopic dermatitis may develop allergies to certain types of mould.

Prevention of Atopic Dermatitis:

While it may not be possible to completely prevent atopic dermatitis, there are measures you can take to minimise your dog's exposure to allergens and reduce the severity of symptoms:

1. Allergen Avoidance: Identify and minimise exposure to common allergens, such as pollen, dust mites, and mould spores. Regular cleaning of your dog's bedding, vacuuming, and maintaining a clean indoor environment can help reduce allergen levels.

2. Diet: Some dogs with atopic dermatitis may benefit from a hypoallergenic or limited ingredient diet. Consult with your veterinarian at Newstead Vets to determine if dietary modifications are necessary for your dog.

3. Regular Bathing: Frequent bathing with a gentle, hypoallergenic shampoo can help remove allergens from your dog's skin and coat. However, it is important not to over-bathe, as excessive bathing can strip the skin of its natural oils and worsen the condition.

Treatment Options:

1. Medications: Depending on the severity of the symptoms, your veterinarian may prescribe medications to manage atopic dermatitis. These may include antihistamines to reduce itching, corticosteroids to control inflammation, monoclonal immune therapy (Cytopoint) or immunosuppressive drugs to modulate the immune response.

2. Allergen-Specific Immunotherapy: Allergen-specific immunotherapy, commonly known as allergy shots, can be an effective long-term treatment option for atopic dermatitis. It involves gradually exposing the dog to small amounts of the allergen to desensitise their immune system.

3. Topical Treatments: Topical treatments, such as medicated shampoos, sprays, or creams, can help soothe the skin, reduce inflammation, and provide relief from itching. Your veterinarian can recommend appropriate topical products based on your dog's specific needs.

4. Environmental Management: In some cases, environmental modifications may be necessary to reduce allergen exposure. This may include using air purifiers, keeping windows closed during high pollen seasons, and avoiding areas with high mould concentrations.
