You may want to get his examined to check for Collapsed Trachea (Forpaws also mentioned collapsed trachea).
I have an 11 pound dog who used to honk a lot and I was told it was a reverse sneeze, then I switched his collar to a much wider, padded one and the reverse sneeze stopped. I have a feeling the old narrow collar with his pulling was doing damage to the cartilage rings of his trachea. We work on his pulling, it's a constant job.
A harness may help too. Although it seems that the issue may be genetic, I do think that damage can be done though with pressure on the trachea from leash pulling.
