What Is The Best Allergy Medicine For Dogs? A Comprehensive Guide

When it comes to managing dog allergies, veterinarians often suggest using Cetirizine, which is available under brand names like Zyrtec® or Reactine®. This over-the-counter antihistamine is widely favored. On the other hand, Claritin® can also be employed, but it’s not the primary choice among veterinarians. This is because certain formulations of Claritin® may contain decongestants like pseudoephedrine, which can be highly toxic to dogs. Therefore, caution is advised when considering Claritin® for dogs.

When it comes to choosing the safest antihistamine for dogs to treat skin allergies, there are a few options available. Cetirizine, commonly known by the brand name Zyrtec, can be administered at a dosage of ¼ to ½ mg per pound of body weight. For example, a dog weighing between 30 to 40 pounds could be given one 10mg tablet twice daily. Loratadine, sold as Claritin, is another option, with a recommended dosage of ¼ mg per pound. So, a 20-pound dog could take half of a 10mg tablet once daily. Lastly, Clemastine, available under the brand names Tavist-1 and Antihist-1, can be given at a dosage of 0.02mg per pound. For instance, a 65-pound dog would receive one 1.34mg tablet twice daily. These antihistamines can help alleviate skin allergies in dogs, but it’s important to consult with a veterinarian to determine the most appropriate choice and dosage for your specific pet.
