Where I worked, it was $85, but it was a full show groom, meaning the ears were thinned out, feet trimmed, tail end trimmed, shoulders etc. thinned out as needed and the dog combed out from head to toe, ears cleaned, teeth scaled and nails done.
I've seen other goldens done locally and usually they still have giant ears with crimpy hair all behind it (in one case the groomer just trimmed the long hair to the shape of the ear, looked very strange), feathers all hacked off, feet still shaggy and sometimes the tail all cut to one length like a setter. Usually they're not well bathed either from what I've seen, they've been rinsed with shampoo and it's been rinsed off, but the coat doesn't feel 'clean' like if they've actually been scrubbed and washed off. Then there's the 'clip' some groomers do where they just shave off the whole dog and leave the head natural but don't even try to get a straight line in the process
What I do at home now when I get time is thin out the ears, trim up the feet and bath, not as fancy but it does the job. Bender is the only hairy dog really here, other than Ticket's ears, for him I think I'm going to get a stripping blade and keep his ear fluff short - he has upright ears when they're bald.
