You CAN train her for 15/20 minutes each day. It will take her a little longer to grasp it but since Boxers are smart breeds I'm sure she would have no problem.

I dont even know wether or not to offer help. Your obviously not going to give her to rescue. So whats better for Daisy , a home where she is kept outside with little attention. Or the home where she would possibly be taken better care of but turned into a breeding machine?
