I can't whistle either, and I have wondered if that works..There have been times when we have been outside & Samson wouldn't "come" when i called and Marq would whistle and sure enuf, Samson runs to him...Something for me to think about I guess..

Sounds like you are off to a good start & like Serendipity said, do short sessions,,Boxers get bored easy
