Sophie is my 3 yr old Mini Aussie. She knows the standard tricks, with a few more expert tricks. Her Frisbee is her favorite toy at the dog park. She loves to fetch the frisbee, but her return is horrible. She will go get it, then run right past you and trot off somewhere. Then I have to go get it and throw it again. I realize going to get it from her has created a bad habit for her... but I have no idea how to get her to stop running past me and actually bring me the frisbee so I can throw it again, and again. Anyone have any suggestions?
