He doesn’t have an off switch. I can call the other two off if they’re in something they shouldn’t be in. Usually. ;~)
My vet has a Blue Heeler that’s like that. Once she gets on a cow she won’t come off. He has to keep a shock collar on her. The funny thing is that she knows when it’s on, so she behaves like a perfect angel, but if he leaves it off she knows he can’t do anything and gets after that cow like a Tazmanian Devil. I don’t think Beagles are that smart. ;o)
