YouTube - "It's Yer Choice"
I've been working it with my dogs and especially with Forest and Carl.
I think I made a terrible mistake though

as I've been working this not only with food but with toys, objects and all kind of things.
Anyway, Carl has come to a point that not only ignores things like in the video but also doesn't play "catch" any more and waiting for me to give him the toy in his mouth or wait until I say "ok play go go go".
My problem is that he seems confused when I say this and looks at me for a couple of seconds and then he goes for the toy. You think that this is problem that I should change?...and if yes how??
