Causes & Symptoms of Dog Allergic Dermatitis Explained

Section 1: Causes of Canine Atopic Dermatitis

1. The internal causes of atopic dermatitis in dogs include genetic predisposition, allergic tendencies, and hormonal imbalances.

2. External factors contributing to atopic dermatitis are quite diverse and can be categorized into seasonal and nonseasonal environmental elements. Dogs may experience allergic reactions upon inhaling dust, dander, or consuming certain foods like horse meat, ham, or dairy products. Additionally, injections of certain medications, mosquito bites, parasitic infestations, and infections can also trigger allergic responses.

Internal factors typically refer to a dog's genetic makeup, hormonal irregularities, and allergic constitution. External factors are more widespread and can exhibit a clear seasonal pattern. For instance, allergies triggered by pollen, dust, mites, dander, spoiled meat or milk, injected medications, sera, mosquito bites, exposure to chemicals, or excessive sun exposure can all lead to canine dermatitis with a distinct seasonal occurrence.

This condition is most common in dogs between the ages of 1 to 3. The initial symptoms often appear around the eyes, on the paws, armpits, groin, perineum, and between the lower back. Affected dogs primarily exhibit severe itching, localized redness and swelling. Other symptoms may include papules, scales, and hair loss. Prolonged allergic reactions can lead to hyperpigmentation, thickening of the skin, and the formation of lichenification and wrinkles. Chronic itching may present with mild symptoms or resolve on its own, while severe cases may require treatment lasting over a year.

Itching and rash are the primary symptoms of atopic dermatitis in dogs and cats. Allergic reactions to medications are not uncommon in veterinary practice. For example, dogs may develop rashes, drooling, swelling, and itchy sensations around the eyes, lips, or abdomen after receiving injections of vitamin K1, K3, or intravenous treatments with herbs like Houttuynia cordata.

Food allergies are quite common in dogs. If a dog shows signs of an allergic reaction to a particular food, it is crucial for owners to modify their pet's diet to prevent recurrence of the allergic response.

Understanding the causes and symptoms of canine atopic dermatitis is essential for pet owners. By being aware of potential allergens, you can take proactive measures to protect your furry friend. Recognize early signs of allergic reactions, implement preventive measures, and seek timely treatment to ensure your dog's comfort and wellbeing.
