How do you call him? When we become frustrated, or we expect to be frustrated, that tone carries in our voices...and no self-respecting dog will answer to that tone of voice.
Do you REALLY want him to come to you?
You have to call the dog as if you GENUINELY want the dog at your side. It is not a chore. There are no time limits. This is not a scenario where I NEED the dog to appear within three minutes...
This is a scenario where you need the dog to be *driven* to appear within seconds.
Start with a crazy, happy voice, reward with sharp cheddar cheese. Rinse and Repeat!
Amy and the dogs,
Jack - male GSD b. 8/9/10

RIP Mattie - female GSD 10/18/02 - 7/24/2013
