Can someone offer up any advice, my two year old lurcher seems to have lost the drive to actually catch. He'll do the leg work and chase but seems to give up once he's close enough, or sometimes he doesn't chase at all. Last season he was spot on. I don't want to give up on him as he really seemed to enjoy it right up until end if season this year. Any help would be useful. I'm wondering whether it's worth getting him back out with an experienced dog as we did as a pup to show him the way again?
