went out with my mate today for almost 3 hours, the young dog worked great, he didnt mark any holes at all but some looked good to us so we netted up and droped in the ferrets, nothing at home so i was well happy with the dog for not false marking, ferreted about 4 big warrens in all and got nothing, we were up on high ground so cant think why there was nothing about, (the ferrets are good workers so it wasnt a case of them not working) on the way back to the van and the dog marked a wall we put a few nets on where it looked right and got 2 rabbits.
