I've drilled obedience training into my 18 month old lab Luna. I take her out several times a week for training and try to give her some type of training, even if it is only to pick up an object and hold it, at least once each day. So I think all of this has contributed to her being very responsive when wildlife shows up unexpectedly.
A couple of months ago a black bear appeared on a forest road and while my little mix started giving chase, Luna spun around instantly when called and returned to me. Several months before that we encountered a porcupine and once again she initially gave chase but then turned around immediately as soon as she was called.
She loves the obedience training and I love working with her.
