Luca my 9 month old German Shepherd has been ignoring me when i call him at the dog park(we are always alone when we go so no distractions, and its not new because we go every day). He comes when we are at home, and when we are in our yard. But when it comes to the dog park he just does not want to listen and this is a big problem. We dont want to get kicked out of the dog park. He is not food motivated so using treats during training does not really work. And he looses interest in toys fairly quickly. I have been reading and reading up on this subject and have been consulting Ceasar Milan ad Victoria Stilwell on things I should do. I was wondering what everyone here has to say before we formulate a trainging schedule to correct this problem.
