Does any one know where to get a reasonably priced ionic pet brush online as I live in Canada? Do they work? Ads suggest it is like a waterless bath. I have read all past posts and sharperimage no longer carries their's. I have read about the brass needle CC brush, but I was looking for one that takes a battery/ies. I also read that a Dr. said it was unhealthy to breath the ozone. Is this correct? How does your dog/s like it? Is it worth buying? Thanks in advance!
