We have to join the group with itching - she is driving me nuts so it has to be miserable for her. I did give her 1/3 tsp Childrens Benadryl which makes her sleepy, but she does not scratch. She isn't drugged sleepy, she will just take a normal doggie nap and if I move, then she is up and moving too. However, she starts scratching the second she wakes up. Chestermama mentioned above if benadryl helped it wasn't food allergy; what suggestions or ideas do you have?
I bought an Oatmeal Shampoo & Rinse for her and have been using it since June. When this happened in June, I had the groomer give her an oatmeal bath and the problem went away until now. Just a note, the product I purchased makes her hair impossible to manage, she looks like a wild child it is so fly-away
