As the man said,,sounds like your doing fine, i like to walk up on squatters with the lamp on with pups,,and if the bunny bolts try to give a command as soon as the rabbit moves,,that way he associates your command with the rabbit running,and him running,, it helps to be able to send him down the beam on squatters later on that command,,ps Id offload the not so keen pup and just pump all the work into the keen one, he'll be twice the dog he is now by the end of the season with all the work,,Best of luck pete,,
Dogs mature at different ages, I've seen dogs not clicking until they are 18
