Hi Janice,

Allergies are very complicated and frustrating. I always recommend treating them with multiple modalities and by combining them, a greater chance of success can be achieved. Antihistamines can be valuable in this process but as it turns out, some animals respond to certain types and don't respond to others. We have created a resource with instructions and dosages to follow so you can try this as a treatment, "Antihistamine Therapy for Your Dogplease read the instructions carefully. I also have an article that reviews the different treatments you can use and the theory behind them for treating allergies, "Dealing With Your Pet's Allergiesand I encourage you to check out our video on allergies, "What You Should Know About Over-the-Counter Antihistamine Use in Dogs and Cats"

Thanks for your question and good luck!
