Have you tried Pet Silk? I use it, and love it! It is great, and pretty affordable when you buy the shampoo and conditioner together. It comes in awesome scents such as mountain berry, tropical forest, cucumber melon etc. But it doesnt just smell good it actually leaves your dogs coat soo soft and nice. I sell it on my website. Alot of people here also like Plush Puppy, Chris Christiansen, Cranberry Fields but I will let someone else chime in for those since I havent tried them! Good luck with your shampoo search!
