I thought Nugget was growling at me, but it sounds more like gargling in his throat when he exhales, or chest or sinus congestion. I noticed tonight while trying to take a pic of him and Steven pointed it out while holding him. He doesn't act sick or lazy, or anything at all that would lead me to believe something is seriously wrong, but still the odd sound bothers me. Does anyone have any ideas what could be up with my gentle giant?
