I tried groomer after boutique after groomer looking for a good cut for our yorkie poo Rocky. It took two years seriously. One cut was so awful, Rocky wouldn't go for our after work walk for 6 weeks. He hung his head in misery or embarrassment not sure which. Yorkie-poo's can be difficult I realize that. Rocky has more of the poodle hair and the groomers like to "groom" him for $40.00 then send me home with a dog that was cut to the skin. He was not matted and they would tell me that as we visited before I ever left him.
Then one great day I found Tammi at Pet Smart. Rocky looks amazing, does not mind going to be groomed. Kisses her ( I watch him behind the glass). The cost is $35.00 and I tip her well, she is very, very good. This fall I got Carlie the Yorkie.....wow! Carlie is gorgeous when I pick her up.
It doesn't matter if it is Pet Smart, Petco, the vet or one of the boutique shops. If you find a good groomer, Yippee! Tip them well, and hope they don't move or get tired of grooming your furbaby.
