Actually it sounds more like a smokers hack than a cough and he only does it when he is around his woman, or running over to her. He can run around and not do it, and quite often he doesn't do it at all. Could he be sick with something or could this be some weird mating thing? He seems fine otherwise, but I haven't taken his temperature. A side note, he never has had much of a voice either, his bleet is very squeaky and quiet and he doesn't seem to be bleeting much right now anyway. Any advice? Thanks!
