You know, I think when she is off leash she thinks she is always in the Playground (off leash) mode. She is confused therfore when you insistently try to fetch her as she is not done with her off leash run. My small standard red thinks like this so I know what you mean. Only his problem is car chasing which he reinforced prior to being with me; I had to buy a shock collar though it is not a cure for his mind, it does keep him alive with me. I do have a constant push from him to be dominant that I have to keep in check. Sounds like we may have comparable dog personalities??
