The best thing for any dog that is having a behavioral issue is talking with a trainer. I would recommend getting a trainer to come to your house to see what is going on with Spirit and look for triggers. It is difficult to say what is causing this behavior without actually seeing her in action. Thank you for using Petco Pet Education Center, formerly Petcoach.
