I've heard http://www.dogsbody.ie/
are very good - you'd want to ring now for an appointment in say Jan/Feb. The lady there also recommends a lady in Bray and a lady in Ringsend so if you want those contacts I can pm them to you/or if you're talking to the lady in Dogsbody.
We go to Doggydoos in Balbriggan and find them quite good. Paddy & Faye are pretty well qualified.
There's also http://www.wendenkennels.com/
- we went there a few times and whilst they did a decent job, for our dog (a Lhasa Apso) it was just a very generic cut rather than one tailored to her breed.
I'm sure there's more others will suggest/recommend
