I fell in love way back with the Crazy Pet Baby Dog Shampoo and Spray Conditioner. I just love the way it smells and no matter what, I always go back to it. I like the look of their bottles as well. Now that I am bathing 6 at a time, I have gone to the Dove from Sams with a PUMP top, shampoo and conditioner. I still finish them in crazy pet on their heads and for the scent. I use the spray conditioner every time I brush. Everyone loves the way they feel and smell (but especially, I do.) Luckily, these guys have good silky coats, (little to no matting) and even though they spend a good bit of time in the yard, the 'stuff' brushes right out. I bathe them once a week (2 hour job), but mainly I try to make sure they are rinsed well.
There is my opinion, I think good rinse, spray conditioner and best dog food make for the best coat. But I won't dismiss the possibility of Luck
