In between baths I use a spray in conditioner called GloCoat that is supposed to help detangle also. It smells really good and makes his coat soft...it also says it repels dirt, dust and urine.
I got it on the petedge website. If you have not been there, it is great. I got some petsilk products there, as well as a BIG package of wee pads-most of my stuff I ordered from there. You can get toys REALLY cheap.
I am needing to do another small order soon, and I cannot wait! My breeder told me about it. They have just about anything you would want.
