My dogs with ct did well in water to calm them down, my one livedto go outside but usually would be so happy to see someone he would go into an attack. The summer was always worse, even if not hot in my house, I had oxygen at home it seemed to help for attacks. He could no longer go in car or out during the really hot day. 
I used these to keep them cool they really worked well might work for your do too as opposed to a bath. You can buy them online or at a sporting goods store. I know how devastating ct can be, I'm so sorry. We need to stop bad breeders and our loved pets wont suffer. If I knew then what I know now.
