Thanks for using Petco Pet Education Center, formerly Petcoach! When using products like Benadryl to reduce anxiety and to help sedate the patient a bit, I prefer using them 15-30 minutes before. We unfortunately cannot prescribe a specific dose of a medication as this requires a patient doctor relationship which requires an in-person evaluation. However, this is something your veterinarian could prescribe as they have evaluated her. Keep in mind that Benadryl is not commonly used in cats for this purpose. I would recommend another product such as Feliway which you can find online or over the counter at your local pet store and this is likely going to be effective for this purpose. Best of luck!

    I am very sorry, but we are not in a position legally to give out dosages. In order to do legally so we would have to have a patient-veterinarian-owner relationship with you. You should contact your vet's office for a recommendation as your veterinarian also knows your dog and the potential risks for your dog receiving this medication.
