Ignore the whining, as hard as it is to do, but you are just playing her game by letting her out when she whines...Boxers are smart, she's figuring out if she whines enuf, you will let her out..They will stop, gets tiring making all that noise..Lol....Just ignore her, as cruel as it sounds...Is she whining when you put her in at bedtime or is this during the day? Cos if you are there, no reason to keep her in the crate..At nite, give her a toy, maybe turn a radio on low for her and just leave the room....
