A sanitary clip to me is clipping out between the hind legs and right around the anus. It does not include trimming belly, feathers, etc. The more specific you are to the groomer, the better. There are very few "real" cuts, and many people ask for a cut without really knowing what it is or means to that particular groomer. Puppy cut for instance...the only REAL puppy cut is on a poodle, under 1 year old in the show ring. TONS of hair, and totally not what clients want..(least I have never had one wanting that true cut). Its just a generic term now, and means different lengths to different groomers. Do be specific as possible, show the groomer what you mean and what you want clipped and how short you want it. Also, just a thought..if you haven't been having any troubles with poo and such getting caught in those places, it can be better to leave it unclipped. Sometimes once its clipped, as its growing in its is worse at catching everything and you have to maintain that clipping much more often because of it. Kinda the "if its not broke don't fix it" saying. Beautiful pup you have there.
