I have a 1 year old boxer/foxhound mix and she has some serious behavioral issues, and is a bully. She has left several bruises all ovee my body from pinching my skin when she doesnt get her way or if she wants me to do something and i dont do it when she wants me to. She barks at every little thing, she gets plenty of exercise and has a pool that she plays in, she will play roo rough with my other dog to the point i have to separate because when my other dog is done playing, she will conrinue.
