I am not sure about the Plush Puppy in TN, but the NY distributor has product. They were at the Javits Center this past weekend in NY. I think it is originally from Australia. Perhaps the TN distributor is closing up?
I also like Chris Christensen shampoos and conditioners and their finish spray. But I think it all depends on what works for your particular dog's needs. I tried Coat Handler, but it left my girl too oily, but it is great for my bichon - so I think you need to see what works for you. I've heard great things about Vellus and Plush Puppy so I may try them sometime.
