Ask the Vet: How to Treat Dog Allergies Safely
Itchy paws. Red skin. Upset stomach. When your dog isn’t feeling their best, allergies could be to blame.
While people often experience sneezing or congestion, dogs show allergy symptoms in different ways—through their skin, stomach, or ears. Whether it’s pollen, dust, mold, or food sensitivities, allergies can be frustrating for both you and your pup.
Here’s what you need to know about recognizing and managing dog allergies, including safe at-home remedies and when to call your vet.
What Are Allergies in Dogs?
Allergies are an overreaction of the immune system to foreign substances—such as pollen, dust, mold, or certain foods. In dogs, this response is often triggered by environmental allergens that build up on their skin and vest or enter their system through breathing or ingestion.
Unlike humans, who usually experience allergies through sneezing and nasal congestion, dogs often show symptoms on their skin, in their stomach, or through ear and facial irritation. This is because a dog’s mast cells—responsible for releasing histamine during an allergic response—are most concentrated in these areas.
Common Symptoms of Allergies in Dogs
Dog allergy symptoms can vary, but some of the most common include:
- Persistent itching and scratching
- Red, inflamed skin or “hot spots”
- Excessive licking or chewing of paws
- Frequent ear infections
- Watery eyes or increased eye discharge
- Sneezing
- Vomiting or nausea
- Diarrhea
Some dogs may vomit nearly every day during peak allergy season, while others develop rashes or ear irritation that leads to head shaking or scratching.
At-Home Treatments for Dog Allergies
While you should always consult your veterinarian for a personalized treatment plan, there are several ways to help relieve your dog’s allergy symptoms at home.
- Topical Relief: Baths and Rinses
One of the simplest ways to help your dog is by removing allergens from their vest and skin.
- Plain water: A quick rinse with lukewarm water can go a long way in washing off pollen, dust, and other irritants.
- Hypoallergenic shampoos: Choose gentle, non-drying shampoos designed for sensitive skin. Oatmeal-based options are a popular choice for reducing itchiness.
- Soothing rinses: In between full baths, a quick rinse or soak with an oatmeal-based product can help ease discomfort.
- Topical sprays: Look for over-the-counter sprays containing pramoxine, a mild anesthetic that helps reduce itching and discomfort.
Aim to bathe or rinse your dog at least once a week during high-allergen seasons, or more often if symptoms persist.
- Oral Antihistamines
Some human medications can be used to treat mild allergy symptoms in dogs—but only under guidance from your veterinarian.
Diphenhydramine (Benadryl): A common option, given at 1 mg per pound of body weight, up to every eight hours. For example, a 25 mg tablet can treat a 25-pound dog.
Chlorpheniramine: Another over-the-counter antihistamine. A typical dose is 4 mg, given twice daily. This is generally safe for dogs, but still consult your vet first.
Note: Not all antihistamines are safe or effective for all dogs. Do not give your dog allergy medication intended for humans without speaking to your veterinarian first, especially if your dog is on other medications or has preexisting health conditions.
When to See the Vet
If your dog’s allergy symptoms are persistent, worsening, or interfering with daily life, it’s time to reach out to your vet. They may recommend:
- Prescription antihistamines
- Anti-inflammatory medications or steroids
- Medicated shampoos
- Blood tests or allergy testing
- Long-term treatment options such as immunotherapy
Left untreated, allergies can lead to secondary infections, chronic discomfort, or behavioral issues. Your veterinarian can help identify the root cause and tailor a safe, effective plan for your dog.
