You have got to try Pet Silk shampoo and conditioner. It comes in amazing scents. I sell it on my site;
PureCanine.com right now I am having a 2 day sale, use the coupon code 5off and get 5% off your order. I am not just bragging it up because I sell it. It will leave your dogs coat soo soft and shiny, and the scent will last for some time. Congrats on getting a Yorkie!
