Good advice from CharlieC there.
IMHO the ealy days of a lurchers working life arent about sport,they are about getting results (kills in other words) get as close to the rabbits as possable and give the rabbit as little chance as possable,has your dog ever been ferreting and allowed to catch a bolter or hold one in the net,that generaly gives them an idea of what lifes all about.Good luck [bANNED TEXT] the more you lamp an area the harder the rabbits become to catch and try finding some bigger fields that might aid your dog.
