Hi. I'm Dr. Lee and will do my best to help.
If Benadryl helps with the itching, then the Benadryl can be given life long, on an as needed basis. Another way to test for allergy is to do skin testing and then follow through with skin allergy sensitization injections, which can take years to get to the right response. Skin testing is usually done by board-certified veterinary dermatologist. You can find one here: www.acvd.org
Please let me know if you have any questions or concerns. Thanks.
Is it true that I give my dog 1mg of benadryl per pound? also Is there anything else you would suggest I can do to help her. What should I do if it doesnt get any better? It has already been 3 day that i have given her benadryl. How many days in a row can i give this to her? Thank you for your advice
Yes. The dose of 1 mg per pound is good. Give every 8 to 12 hours.
Benadryl usually works within a few days. If you do not see any improvement, then you need to change anti-histamine, like going to Zyrtec. If Benadryl works, then you can continue using that every day for months to years. There is no harm in using Benadryl.
Zyrtec dose is 0.5 mg per pound. So half of Benadryl. To be given every 12 hours.
Since Benadryl is working, I would suggest to try giving it every 6 hours and see if that can control the itching gap.
THANK YOU VERY MUCH!!! Your advice will be a big help.
