Oh honey I am so sorry for what that groomer put you and Princess through
I know you have heard it before that it is only hair and it will grow back (and it will) But, I have been in your shoes and it doesn't make you feel any less mad or upset. It galls me that we take our babies to a groomer and tell them to a "T" what we want and they don't listen. I know there are good groomers out there, but they are almost impossible to find. The last time I took mine to a groomer, she not only didn't do their cuts like I wanted but they acted strange for almost 2 days. I never took them back and do it myself now. One of the girls I work with used the same groomer for her pom and took him in about 3 months ago, got the call he was almost ready and she was close to the ladies shop when she got their to pick him up. The groomer wasn't expecting her that early and didn't see her come in. She heard the groomer talking really hateful to her baby and he is a very sensitive little pom and she had shaved him almost to the skin and gapped him up. Needless to say she is learning to groom her dog now herself and will never take him back. What makes it bad is that this groomer is one of our customers at the bank and we have to deal with her weekly
Go with your gut feelings as they usually are right and I am so sorry about what happened to Princess and I hope she gets back to her normal happy self soon.
