Grooming school can be really expensive! I looked into it out here in SoCal and it was ridiculous along with my other schooling. I just got a job with PetSmart and they sent me to their school for free. It was 4 weeks long and 12 weeks in store training. I'm still at the end of my apprenticeship, but it's been great! Great benefits and a heck load of safety policies all designed to keep doggies safe
But I warn you it varies from store to store. I've seen some crappy stores, I am lucky to be in a good one. The best thing is that you can transfer out of stores easily.
