Okay, I have tried everything. Penny has such sparse hair, if I put her top knot up with just one band it all comes out as soon as she shakes. Other than bands, can I get this hair to stay up any other way? Here is a photo of how I do her hair, I change the bands everyday, if I don't it gets knotted. I've been a groomer for 33 years, but never had a yorkie to worry about, always had poodles.
Here is a photo of how I do her head. She hates her hair being done and her photo being taken, so she looks distraught!
