A.M.
I would probably be your groomer (mobile) & since 1989, but I'm not in IL and out of work between hand surgeries. Some advice: Bring a few photos, make many clear notes w/ specifying what length you would like each area, etc. Not all groomers do a "puppy cut" the same or there can be 100 different ways to do a Shih Tzu! Voice your frustration, be specific and ASK IF YOUR DOG MAY BE HARD TO HANDLE ALSO? Some people mix better w/ certain animals than others! Try for a "seasoned" groomer, not a "new one" and not "crabby & burnt out"! Another option, although I HATE TO PROMOTE (STORE CHAINS) IN THE TRADE
BUSINESS; but, you could take him to Pet Co or Petsmart and when his hair comes out wrong, refuse to pay, but voice that this IS YOUR INTENT to the grooming shop manager first. I much rather advise you to stiff a chain that really hurt us small business owners in the mid 90's than to advise this with a small business owner, like myself whom is COUNTING ON THE $30- from your Shih Tzu. Next option, drive to me in MI, get into a grooming school or BEG A OLDER, TIRED groomer to take you in and teach yet another one of our own breeds w/ OUR OWN STYLES . GOOD LUCK
