Hey Gunnery;
Yes, I do worry about that. But until now, Nos has (to my knowledge) not chased deer. (His brother has... so I know they will... Just that Nos has not...)
When I asked Nos to do the blood tracking, it was under very specific conditions. First & foremost, Nos was on leash from start to finish. Second, there was blood present where the deer was hit initially. So, if I'm thinking correctly, Nos knows deer are now part of the game, just that he is to track blood.
I sure hope that he doesn't get it in his head that it's okay to chase a live deer with NO blood trail... If that happens, I will consult with the breeder & take the appropriate measures. For now, I'm immensly proud of the job Nos did on his first blood track!
Cheers
Jay
