Obedience training for Loki

For a laugh - and because the show is about a mile from my house, and because I've put Grace in the breed show as she can't do flyball any more..... I've entered Loki in beginners and novice obedience!!!! I must be mad - he's not had any obedience training as such, but he takes after his dad and just does natural heelwork, that I thought..... why not. At least then I'll see what he is capable of and whether it's worth finding a good trainer to work with to get him up to proper show standard - or not!!!!
