Hi
We go to a gundog trainer in Winkhill near Leek which I dont think is that far from you. She does gundog grade training through the gundog club or one to ones.
We dont work our dogs but take them weekly to the training where they look at sit, wait, recall, retrieve, hunting etc. Not sure what level of training you are after.
My 2 our working cockers but I do know a number of show cockers that go to her for training as well.
If you want more details let me know.
