Zyrtec vs Claritin for Dogs?
As a dog owner, you want to do everything you can to keep your furry friend happy and healthy. One way to do that is to make sure they’re not suffering from allergies. Just like humans, dogs can experience allergies to certain substances, causing discomfort and even pain. Thankfully, there are medications available to help alleviate allergy symptoms in dogs, such as Zyrtec and Claritin. But which one is the better choice for your furry friend? Let’s compare Zyrtec vs Claritin for dogs.

Zyrtec for Dogs: Fast-Acting Relief
Zyrtec, also known as cetirizine, is an antihistamine that works to block the effects of histamine in the body. Histamine is the substance that causes allergy symptoms like itching, sneezing, and watery eyes. Zyrtec is a fast-acting medication that can provide relief to your dog within 1-2 hours after administration. This means that if your dog is experiencing an allergic reaction, Zyrtec can quickly alleviate their symptoms.
Claritin for Dogs: Long-Lasting Relief
Claritin, also known as loratadine, is another antihistamine that works to block histamine in the body. Unlike Zyrtec, Claritin is long-acting and can provide relief for up to 24 hours after administration. This means that if your dog has seasonal allergies or chronic allergy symptoms, Claritin may be a better choice for them.
Potential Risks of Claritin for Dogs
While Claritin is generally safe for dogs, some forms of Claritin contain decongestants such as pseudoephedrine, which is toxic to dogs. If you decide to give your dog Claritin, make sure to choose a form of the medication that does not contain decongestants. Additionally, always consult with your veterinarian before giving your dog any new medication, including Claritin.
Conclusion
Both Zyrtec and Claritin can provide relief to dogs suffering from allergies, but they have different strengths. Zyrtec is fast-acting, making it a good choice for dogs experiencing acute allergic reactions. Claritin is long-acting, making it a good choice for dogs with chronic allergy symptoms. As always, consult with your veterinarian before giving your dog any new medication. With the right medication and care, you can help your furry friend enjoy a happier, healthier life.

What do vets use for dog allergies?
Vets may use a variety of treatments to provide relief for dogs with allergies, depending on the specific cause of the allergies and the severity of the symptoms. Some common treatments for dog allergies include the following:
Antihistamines: Antihistamines are medications that can be used to relieve the symptoms of allergic reactions, such as itchy skin and watery eyes. They work by blocking the action of histamine, a chemical that is released by the body during an allergic reaction. Common antihistamines for dogs include diphenhydramine (Benadryl) and cetirizine (Zyrtec).
Corticosteroids: Corticosteroids are medications that can be used to reduce inflammation and relieve the symptoms of allergic reactions. They work by suppressing the immune system, which helps to reduce the body’s response to allergens. Common corticosteroids for dogs include prednisone and dexamethasone.
Immunosuppressants: Immunosuppressants are medications that can be used to suppress the immune system and reduce the body’s response to allergens. They are typically used for dogs with severe allergies that do not respond to other treatments. Common immunosuppressants for dogs include cyclosporine (Atopica) and azathioprine (Imuran).
Allergy shots (immunotherapy): Allergy shots, also known as immunotherapy, are a type of treatment that involves exposing the dog to small amounts of the allergens that are causing the reaction. Over time, this can help to desensitize the dog to the allergens and reduce the severity of their allergic reactions.
