If you could make your pet understand one thing, what would it be?

You all know Lily, beautiful but if she sees a hare or rabbit all bets are off. She’s gone. I’ve tried several different trainers and all professional too. It’s the only thing she won’t do. Recall under normal conditions is fine, but the pesky hares and rabbits are too much. She’s 5 in April, she won’t change now. So if there was one thing I wish she’d understand is to come back when she starts chasing.
Oh well, otherwise a beautiful and obedient dog (most days).
