Welcome to YorkieTalk
Seven or eight weeks is really too young to bring a Yorkie pup home. Please watch her very closely for hypoglycemia at this age.
I cut Ellie's hair myself. Groomers don't need a license to cut hair, so some don't know what they are doing. I would also be concerned about abuse and neglect if I left my dog at a grooming salon unattended. There are some good ones though. It is just easier for me to do it myself.
