I started using a flirt pole with Athena about a couple weeks ago. To say she loves it would be an understatement! That being said, she wants to do it ALL the time. Right now she goes out for around an hour or two a day. She has to be dragged into the house to stop. Once inside, she sits and whines at the door. We used to leave it on the porch but she just grabs it and runs off with it when she goes outside. So I put it in my closet. Now she'll go back and forth between the front door and my closet whining wanting to get the pole. It literally is all she wants to do now. Is this normal for some dogs? Anything I can do to curb her fixation on it?
