Its really difficult - the recognised qualification is the City & Guilds, but I see lots of dogs done by C & G qualified people who bear no resemblance to the breeds usual trims. Advantages of C & G qualified people is that at least they should have a full grounding in safety practice, care of the client dogs etc. word of mouth is possibly the best, some really long time groomers who never did the C & G may be the best and most experienced at your breed, or someone who is expert in one or two breeds only, and only does those breeds. Of course, a lot of pet people are completely happy with an everything off trim every time anyway, which only takes a little skill in the safe use of clippers! And fancy sales literature is no guarantee that teh service will be first class, I just think if someone cant be bothered to make sure their first point of contact is tidy, professional and good to look at, what hope have you of your dogs trim being any better?
