Stinky things to Yorkies are like perfume to us. Ever spray some perfume on your wrist and try to get your Yorkie to smell it? They will wrinkle their nose and turn their heads. Watch how fast they will roll in dirty undies if they are thrown on the floor!
I had a little Westie years ago, who dug up rotting fish from the garden and rolled in it. Talk about your "stinky" dog! I spent a long time washing and washing and washing her.
