Recall

Think about the times when you call your dog. Home-time, end of the walk, to stop it meeting another dog, ect. From your dog’s point of view, being called often predicts the loss of something. It is an event that they associate with a negative outcome. Playing games of any kind on your walks is a good way of keeping your dog’s attention. Practising some obedience training is fun if there is a reward in it and it helps to increase your dog’s positive view of a recall. Practice recalls on walks. Randomly call your dog, give them a reward and send them off again. Call them, clip on the lead, reward them and let them go again. Rewards can be praise, food treats, playing a game or with your dogs favorite toy. Use a high value reward for coming back outdoors.

I have a dog who went mad for 'coachies' treat biscuits but my new dog is not that bothered by them. However, I took some advice from here and use tiny bits of cooked liver and she races back to me everytime so far; she actually sits at the fridge when she thinks we are going to do some training, so I would definitely recommend that. I also us a 50ft lead which I just let rail along behind her as she is still very young but it is a goo dsafety net.
