I did not leave Pixie at the groomers until she was over a yr old. I read too many horror stories
So I use to bring pixie to the groomer and stay and hold her or stand by her while the groomer trimmed her up. If you can find someone that is willing to allow you to do that.
I was not comfortable leaving Pixie at all so I didn't until I was comfortable. It is your baby and you need to do what is best for you. If you don't feel comfortable leaving her than listen to that and don't.
