If your dog likes to eat fuzz off of the carpet and he starts acting like he is choking or coughing is he?

Your dog is probebly getting the carpet fibers stuck in his throut, and that is why he is coughing. Change his behaviour, by introducing him to other things such as his chew toy's when he is doing this. Say "No" and mean it. Be consistant. Over time his behaviour will deminish.

duhh

if he's acting like he's choking i don't think joking.
