Skin allergies in dogs, also known as canine allergic dermatitis, occur when a dog's immune system overreacts to specific allergens. These allergies are one of the most common causes of itching and discomfort in dogs and can significantly impact their quality of life if left untreated.
Common Causes of Skin Allergies in Dogs
-
Environmental Allergens
- Pollen, mold, dust mites, grass, and other environmental factors can trigger seasonal or year-round allergies.
-
Food Allergies
- Certain proteins (like chicken, beef, or dairy) or other ingredients in a dog's diet can lead to allergic reactions affecting the skin.
-
Flea Allergy Dermatitis
- Many dogs are allergic to flea saliva, which can cause severe itching even from a single flea bite.
-
Contact Allergens
- Reactions to specific shampoos, cleaning products, or materials like wool or synthetic fabrics.
Symptoms of Skin Allergies in Dogs
- Persistent itching, scratching, or licking.
- Red, inflamed, or irritated skin.
- Bald spots or hair loss due to excessive scratching.
- Dry, flaky, or scaly skin.
- Bumps, rashes, or hot spots (raw, inflamed areas).

- Secondary infections from excessive licking or scratching.
How to Manage Skin Allergies in Dogs

Environmental Changes
