I'm going to have to disgree on the mentality being a cur breed. If you have never been around one you would not understand what I mean. I'm not talking tracks or what ever but take a hot fence my female is a master escape artist she will literally stand there at it thinking how to avoid it and get out. Just things like that. You would truly have to be around one to understand what I mean. Tbob your thinking smart and yes there are some durn smart dogs out there but for a dog to really think I don't see as much.
The velociraptors in Jurrassic Park did that exact same thing, I wonder if some of that way back in the lacy's history?
