One great idea I have learned over 8 years of Yorkie cuts- If I ever go to a new groomer- I have drawn a picture of a yorkie on a 3x5 card and I mark in red only what they are allowed to cut, then there is no confusion and they better not touch anything else. They keep the card on file and I find this works where nothing else ever did ( even threats!)
This had worked now for 7 years!
