Christopher Vicari and Manny Comitini's
the color coordinated canine Show clarity
The above two got many mentions on predominately a show thread.
Here are some of the products I have used and liked
Isle of Dogs – in particular their Gloss Shampoo and Nutrient Masque. Very expensive use for show days or special occasions. Then one of the evening primrose shampoos they have a couple of formulations.
Ives St. Bernard.
Biogroom Silk Conditioner. Great price, and did well with my boys coat.
