Trish, have you played the game at home where you hide a couple of his favorite toys, could be in the garden , or house then you ask him to find them.
We started to do this with some of our dogs. If you sort of drag/rub the toy along the floor without him seeing you, he would soon get the idea of following the trail.I know alot of people who play this game. The dog has to think about what he is doing.
The Kennel Club also keeps a list of training clubs if you contact them they will send it out. You could then go and have a look at what certain clubs do and choose the best for your needs.
