Pet Allergies 101: Food vs Environmental Triggers Explained

Allergies in pets can cause itching, ear infections, digestive upset, and chronic discomfort. Understanding the difference between food and environmental allergies is the first step toward effective management.

Environmental Allergies

Environmental allergens include:

• Pollens, grasses, and molds
• Dust mites or household chemicals
• Flea saliva (flea allergy dermatitis)

Symptoms often include:

• Itching, scratching, or biting the skin
• Red, inflamed ears or paws
• Sneezing, watery eyes, or nasal discharge

Food Allergies

Food allergies occur when a pet’s immune system reacts to a protein in their diet. Common culprits include beef, chicken, dairy, and grains.

Symptoms can include:

• Chronic itching or skin rashes
• Ear infections
• Vomiting or diarrhea
• Poor coat condition

Food allergies are less common than environmental allergies, but they are often overlooked.

Diagnosis and Management

• Veterinary testing can help identify the trigger. This may include elimination diets, blood tests, or skin testing.
• Treatment can involve diet changes, antihistamines, medicated shampoos, or allergy immunotherapy.
• Environmental modifications, such as flea control, air purifiers, and regular cleaning, can help reduce symptoms.

Allergy management is individualized—what works for one pet may not work for another.
