I pay $32 to have my dog groomed : shampoo, clipped, nails (including dew claws), ears cleaned, and anal glands expressed (I'm happy that she does that). My groomer does not charge more if my dog has any mats, but she may end up with shorter hair if so. I have a 10 lb Shih-Tzu and live in MA. I give our 62 lb Yellow Lab baths myself, and taught her to accept a dremel to groom her nails - which I also do myself.
