Atopic Dermatitis
Atopic dermatitis is a common, chronic, and often inherited allergic skin disease in pets, primarily causing intense itching and inflammation.
Detailed explanation
Atopic dermatitis is a type of allergic reaction where a pet's immune system overreacts to common environmental allergens like pollen, dust mites, or mold spores, similar to hay fever in humans. This leads to persistent itching, which can cause pets to scratch, lick, and chew excessively. Over time, this self-trauma can result in red, inflamed skin, hair loss, skin thickening, and secondary infections by bacteria or yeast. Symptoms often worsen seasonally or with increased allergen exposure. While not curable, it can be managed with various treatments, including medications, allergy shots (immunotherapy), special diets, and regular skin care, to improve the pet's comfort and quality of life. Diagnosis often involves ruling out other skin conditions.
