What's going on with Major's bark? =(

Did Major stay in the kennel recently? He may have contracted something there. Also, can you see him while he's doing it.
My Lab/mix, Maggie makes many more wierd sounds than my shep/mix
Smokey. It might be a Lab thing.

Yes - he did stay at the kennel, we picked him up on Jan. 2. He is up to date with his kennel cough and other shots though. My dad heard him bark yesterday and said it sounded slightly less 'hoarse'. (The word he used, I'm not sure if its correct, I guess it kind of sounded hoarse.)
I haven't heard him bark since then.
Yes I could see him when he was barking, everything appeared normal except for the sound. He's not lethargic or acting sick at ALL, not one sign. So I'm not sure.
