You dirty mexicans need to come over to SA and hunt in some real sized paddocks on some real foxes. My big dogs would catch a fox that has a headstart that would wear your whippets out.
If that doesn't get a response then I know your all sick of advising with me, will someone please respond upset to put a smile on my dial? Especially you Jmac. You still got that feral looking rat thing hanging off your chin?
