I live in Vero Beach and my Roxi is a much happier dog after she's been to the groomer.  I have her and her brother (a retriever/chow mix that sheds more than any corgi I've seen) bathed and shaved.  Rox rolls around, plays more and just seems to be much more comfortable, even though she's an indoor dog.  Plus side...the vacuuming of course.  Down side?  Just make sure to leave some fur around the nub.  Shave that area and it's just not a pretty sight.
