just been reading david h post on shildens results thread and he has an interesting theory on why dogs go right, left or up the middle. anybody have any ideas as to why a dog goes right, left or up the middle? anyone any ideas how u can get this out of them or do u think u cant? our sparklin whizz is that severe right hand if shes off the left she comes out the traps and practically turns around to get to the right hand side
