It costs me $32.00 to get my shih tzu bathed, ears plucked and cleaned, nails trimmed, and anal glands expressed. She can get really matted though, as my Akita loves to slobber on her. We keep the hair on top of her head long enough for a top knot with a bow.
Off topic: If you do get a shih tzu you will love your new little lap dog. They are bossy, dominating, little demons with a Princess complex, who know their place in the world and truly believe that everyone else is placed on this earth to cater to their wishes. You should see the look of total shock and disbelief on their adorable faces when they are informed otherwise. They feel they are masters of their domain. They will tell you when to go to bed, then will make you move your feet exactly where they want them, so they can be comfortable as they lie crosswise in your king size bed, (scooting you to the very edge). They will demand your food, then sniff at it daintly for a few moments then give you a look like they did you a favor (and why isn't it filet mignon, mom?), before they grab it (taking half of your finger with it), They will give you a totally shocked look, if you ever use the word no to them. They are absolutely adorable and always act like they are ten feet tall and weigh over 100lbs, instead of 8" tall and 13lbs. My little angel thinks nothing of bossing all of us around, including my 80+lb Akita, who she thinks he is her personal chew toy. She's a Princess, knows it, and has no problem conveying to everyone who comes in contact with her that she is not only a Princess, but THE High Princess.
