I'm not going to guess, but I will say that all my GSDs have respected gates, and even if the gates are open they still know that this is a boundary of sorts. I've had my dogs barking on one side of an open gate before - or at the edge of a property line. I look at this as a territorial behavior, protecting the property, and I wouldn't expect mine to bite just because they were barking. I think there'd be lots of lunging and jumping, with some growling, before a bite came into it. From what I've seen with my dogs though - since I don't know Hondo.
