How do I get him to shoot out after the bumper while just walking? Is this even an issue?
It could be an issue.
To best answer your question to the best of my ability, I'd ask you to ask
yourself a question-
Did you, or do you
believe that your pup was properly Pressure Conditioned?
Don't get me wrong,... just because your dog isn't lunging to every bumper he sees doesn't mean that he's not been properly FF'd, or that you need to get him back in FF' and overwhelm him with pressure.
Thing is BRod if you're doing a Fetch/No-Fetch drill and there's not much effort from the dog to FETCH the bumper it kinda' makes "leave it" a moot command...he's
already "leaving it" ;-)
Can't remember if Stawski goes from the table to the ground or simply starts off on the ground in FF' but if you went from the table directly to the Walking Fetch, it's kinda' sorta' something different to the dog. You're asking the same thing of the dog, but you're asking it on the ground and not on the table.
Maybe reaching down and pinching an ear as you're approaching the first of the 3 bumpers in the line-up may serve as a refresher.
