Is my boxer deaf or stubborn?

[robertb6963]

He doesn't seem to know his name or come. But when I make a funny noise he tilts his head, or when I squeak a toy behind my back his ears perk up. He is a fawn.

I read this link, but I still don't know. Any other tests?

Roscoe does the same I was thynking it was because he is so young I know he can here but is does not come when called for sure AND if I sneak in to check on my kids if her is sleeping w one of them he does not seem to wake up either LOL so who knows
