Don't appologize, that's why we're here. Rich and I don't disagree on this, we just have different terminology for the same vocalization. Your question was a good one, in that it helps us all get on the same page. Standardizing nomenclature is the first step in effective communication. /ubbthreads/images/graemlins/wink.gif
There are very subtle differences in barks, so, as Rich says, be careful when you use them. Unless you are very sure you know the difference between a threat and a challenge bark, you could ruin your stand. And don't initiate the challenge. Only use it as a response to a challenge, and then only sparingly. Make it a wimpy challenge response, or you might scare the challenger off if you sound like a 60 lb. intruder. /ubbthreads/images/graemlins/smile.gif
