That sounds alot better mate, I'l give it ago,
Mate, listen to some of the other lads, in a nutshell its a wank idea, find your dog something to chase, to allow his instincts to kick in. Find a rabbit far out and let the dog use the instincts he has. The dogs drive is triggered by flight of the prey species, having a dead rabbit in a field!!! My bet is you will have to walk the dog to within an inch of it and he will show little interest in the cadaver, get him sighted on something moving and he chase.
