Thanks for all the responses. Today is the third day of DMSO. He is doing very well with it. Tonight he got a bath and brushed and he is all clean and smelling sweet and he knows it. I love seeing him like this. Took last predisone today so we are just waitng to be able to do the Cushing's test. The CC is all over his body, my only hope is that we can still get it under control. Every day is a new day to see improvement. Thanks for all the the support. This is a great community to be part of, if you have to deal with something like this. At least you know you are not alone.
