Yes, exactly this for me! That's what I meant by my going about things the wrong way with Cassie, that retrieving's not top of her to do list, she's had to learn it. It never occurred to me about the difference in priorities in dogs, it's taken me over 2 years to learn that hunting / chasing is what motivates her. That earning her rewards by catching or searching for them is more rewarding than directly from my hand, that the best way to engage her in tug is to drag the toy behind me, away from her, all these things are so obvious now!
From an early age she has been exposed to squirrels, deer and to a lesser extent pheasants, but rabbits and hares are more recent, it's the scent, not the sight that excites her. On Sunday, a training session went a bit wrong, I won't go into how but she was then madly on rabbit scent and a deer shot out of a bush in front of her -- she was still running, but stopped and watched it go, and then returned to us without a recall signal ! That is how that particular debacle came to an end!
It's about me finding away to prevent her leaving my side, which mostly now she stays close to me , it's going to me tough but I am hatching a plan!
