Common Dog Allergies – Symptoms, Causes, and Prevention
Allergies are a common problem in dogs and can significantly affect their quality of life. Allergic reactions occur when a dog’s immune system overreacts to harmless substances called allergens. Identifying the cause, recognizing symptoms early, and implementing prevention strategies can help keep your dog healthy and comfortable.
1. Types of Dog Allergies
Dog allergies are categorized into three main types:
A. Environmental Allergies (Atopy)
- Caused by pollen, dust mites, mold, or grasses
- Common in dogs with itchy skin, red eyes, or sneezing
- Symptoms often seasonal but can be year-round in some cases
B. Food Allergies
- Triggered by proteins in common foods (chicken, beef, dairy, wheat)
- Symptoms include chronic ear infections, skin inflammation, vomiting, and diarrhea
- Diagnosed via elimination diet under veterinary supervision
C. Contact Allergies
- Caused by direct contact with irritants (soaps, fabrics, plants)
- Localized itching, redness, or rashes
2. Common Symptoms of Dog Allergies
Allergic reactions in dogs can manifest in various ways:
- Excessive scratching or licking of paws and body
- Red, inflamed, or scaly skin
- Chronic ear infections or head shaking

Severe allergies may lead to secondary infections or discomfort that affects overall wellbeing.
3. Causes of Allergies
Allergies in dogs can be caused by a variety of triggers, including:
- Pollen from grasses, trees, or weeds
- Mold spores or dust mites
- Certain proteins in food

4. Diagnosing Dog Allergies
Accurate diagnosis is essential for effective treatment. Methods include:
