Macky does, her horrid cocker-spay-fuzz coat needs to be cut down regularly or she's a hot mess. Our groomer at work does it, of course, and does a fabulous job.
I use to see no point in bringing dogs that didn't need trimming or clipping to the groomer until I started working with a groomer... Then she showed me what a huge difference a thorough bath and a good blow out with the dryer can make for any double coated dog, and now I'm proponent of it (if you go to a good groomer). But then again, our groomer is super thorough about blowing out/brushing out dead undercoat, which is hugely important for healthy skin in double coated breeds. Other places might just do a bath and dry, which isn't nearly as valuable.
Keeva gets bathed/blown out regularly, but I do it myself since it's free.
