She is adorable. Look at her show off that new cut.
I wouldn't worry to much. We had a Lhasa Apso named Sparky. He lived a very long time. He hated being groomed. By anyone. Including us. So it is not the groomers most likely. It is just Nadi. She is just like Sparky and hates being groomed.
As far as the nails. We found nail clippers with a light on them. It allows you to see where to cut better. We found them on Amazon.
RE: Nadi's haircut at the doggy salon. it may be her last
