This article will review some of the best OTC allergy medications for dogs, highlighting their pros and cons.

1. OTC Antihistamines for Dogs

a. Benadryl for Dogs (Diphenhydramine)

Remember, while OTC treatments can offer relief, they might not address the root cause of the allergy. Identifying and eliminating allergens from your dog’s environment is the most effective long-term solution.

Best Prescription Allergy Medicines for Dogs

For some dogs, over-the-counter (OTC) remedies or natural supplements might suffice, but for others, especially those with severe or chronic allergies, prescription medications are the best course of action. In this section, we’ll explore some of the best prescription allergy medicines for dogs, their pros and cons, and potential side effects.

1. Apoquel (Oclacitinib)

It’s essential to work closely with your veterinarian to find the best solution for your pet. Regular check-ups and monitoring are crucial when starting a new medication to ensure its efficacy and monitor for any potential side effects. Remember, the goal is always to improve your dog’s quality of life and keep them comfortable and happy.

Best Alternative Allergy Treatments for Dogs

While conventional treatments such as prescription drugs, over-the-counter drugs, and natural supplements have their place, some pet owners are seeking alternative treatments for their furry friends. This section delves into the world of alternative allergy treatments for dogs, highlighting their potential benefits and the science behind their effectiveness.

1. Allergy Immunotherapy (Allergy Shots)

allergy shots for dogs

Allergy immunotherapy, commonly known as allergy shots, is one of the most widely recognized alternative treatments for both humans and dogs.

How It Works: Allergy shots work by gradually exposing the dog to increasing amounts of the allergen causing the reaction. Over time, this can help the dog’s immune system become less reactive to the allergen.


  • Long-term Relief: Immunotherapy aims to provide long-lasting relief from allergies, rather than simply treating the symptoms.
  • Reduced Medication: Successful immunotherapy might reduce the need for other allergy medications.


  • Time Commitment: The treatment involves regular injections over several months to years.
  • Not for Every Dog: Not all allergens are suitable for immunotherapy, and not all dogs will respond to the treatment.

2. Hydrotherapy for Dog Allergies

Hydrotherapy for dog allergies

Hydrotherapy involves the use of water to treat various conditions, including allergies.

How It Works: For dogs with skin allergies, hydrotherapy sessions in clean, filtered water can help cleanse the skin of allergens and soothe irritations. The water’s buoyancy and resistance can also provide therapeutic exercise.


  • Soothing: Water can be calming and can help reduce inflammation and itching.
  • Physical Exercise: The exercise aspect can boost overall health, which might help alleviate some allergy symptoms.


  • Facility Quality: It’s essential to choose a hydrotherapy facility that maintains clean and appropriately treated water to avoid introducing new allergens or irritants.

3. Acupuncture for Dog Allergies

Acupuncture for dog allergies

Acupuncture, an ancient Chinese practice, has been used to treat various ailments in both humans and animals.

How It Works: Thin needles are inserted into specific points on the dog’s body to stimulate energy flow and promote healing. In the context of allergies, acupuncture might help modulate the immune system’s response.


  • Natural: Acupuncture doesn’t involve drugs or chemicals.
  • Holistic Approach: It looks at the dog’s overall health and well-being.


  • Qualified Practitioner: Ensure you consult a veterinarian trained in acupuncture.
  • Multiple Sessions: Multiple sessions might be required to see benefits.

4. Allergen-specific Bathing

Regular bathing using hypoallergenic or medicated shampoos can help remove allergens from a dog’s coat and soothe irritated skin.

How It Works: The act of bathing washes away surface allergens, while specific shampoos can provide additional soothing and anti-inflammatory benefits.


  • Immediate Relief: Bathing can offer immediate relief from itching and discomfort.
  • Versatility: There are various shampoos tailored to different types of skin conditions and allergies.


  • Frequency: Over-bathing can dry out a dog’s skin, so it’s essential to find a balance.
  • Shampoo Choice: Always choose a high-quality, vet-recommended shampoo.

5. Controlled Environment

Creating an allergen-reduced environment can significantly help dogs with environmental allergies.

How It Works: This involves regular cleaning, using air purifiers, and limiting the dog’s exposure to specific outdoor environments during high pollen times.


  • Reduced Exposure: Minimizing contact with allergens can reduce the severity of allergic reactions.
  • Overall Health: A clean environment benefits a dog’s overall health and well-being.


  • Regular Maintenance: This approach requires consistent effort in maintaining a clean living space.
  • Limited Outdoor Time: During peak allergy seasons, outdoor activities might need to be curtailed.

Alternative allergy treatments for dogs offer a holistic approach that can work in tandem with or sometimes replace conventional medication. As with any treatment, it’s crucial to work closely with a veterinarian who can guide the process, monitor the dog’s reactions, and adjust the approach as needed. Every dog is unique, and finding the right combination of treatments requires patience, observation, and a commitment to the dog’s overall well-being.

    Dogs can develop allergies at any stage in life. While some might show symptoms as puppies, others might only start exhibiting signs of allergies as adults. Changes in environment, diet, or even aging can trigger allergy development.
  20. What’s the difference between an allergic reaction and anaphylaxis in dogs?
