My dog has itchy skin and allergies. Benadryl isn't helping. What's next?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | 25 lbs

Hi. Miller has been bad for a week with possible allergic reaction. He is currently allergic to chicken but hasn't been given one as we recall. For 7 days he has been on Benadryl, *active ingredient acrivastine not diphenhydraphine. 5 days - 1 pill a day, last 2 days - 3 pills a day. It is not helping, if anything making things worse. He has symptoms of itchy skin, early conjintivitis, sleeps more and seems tired. What is next course of action?

The next thing to do is go to the veterinarian. If the antihistamines are not working, he may need something stronger. These lesions could also now be infected. Make sure to protect the area from rubbing or scratching and he should wear an elizabethan collar at all times. Have him examined soon.

    Place an e-collar (cone) on Hannah to prevent further scratching. Confirm the Benadryl dose with your veterinarian. If the spots do not resolve, have her examined by your veterinarian to diagnose infection, allergies or other causes.
