Where can i learn to do this, anyone know?

Probably the best thing would be if the breeder of your dog could help, or see if your local breed club runs grooming training.  Our local Airedale club runs a monthly trimming class which is where I learned, topped up with trips back to my girls' breeders to sort out the dodgy bits I'd done wrong.  It takes time and perseverance and lots of studying other dogs and photos, but I honestly would say in the 18 months I've been showing I am now up to par with most other exhibitors, some of whom have been showing a long while.  Be prepared to spend quite a few hours a week working on the coat though, if I don't do a bit of trimming on my girl every couple of days it's easy for the fcoat to get out of shape again.  Good luck!
