FAKE REVIEWS!
Look at how many people are "reviewing" and then look at how many friends they have? Do they have a picture? No. What a scam. They used crap products on my dog that leaves a residue and I ended up having to wash him at home.
Look at the 'unfiltered reviews.' They complain and flag all bad reviews so that Yelp moves them out of their rating scale.
and BTW, these people had ZERO training on how to groom a dog. Ask them what school they went to or rather, what DVD did they watch. Not kidding. At least PetSmart has different groomers, better products and if you are not satisfied, will give you a free groom.
