My dogs will get another (visiting) family member out of bed. "Pyg" guards the open chicken gate, so the hens don't wander out. Unlike Rose she won't think of chicken for lunch, just wants the eggs.
They both get nervous when the horses roll, bc many years ago Ro Go Bar got cast when he rolled (at age 26) and no amount of barking got him up.
And, of course, they guard...and track...and chase.
PLEASE don't give up your dog. All of the suggestions are good. Maybe you can borrow the zap collar, first, if $ is tight.
