Good Trainer for GSD, Rottweiler, Doberman in North Toronto?

Hi everyone

I live in the Markham area. Anyone knows any good dog trainers especially for training big dogs such as - Doberman/Rottweiler/GSD?
I dont mind if it is class or personal(individual) training, as long as it is effective on helping my dog on heeling, stop from pulling/jumping and correct his behaviour on barking at other dogs.

Thank you very much for your help.

What ever ones you do find ( i am no where near you, sorry) be sure to check 'references'

And its not going to happen over night. Its a process which may take a while too.

good luck and I hope things work out.:fingerscr
