Luckyducker..is your pup an Aussi Cattle Dog or a cross? I have one that looks JUST like yours (with the very large ears..haha). We've been told over and over he's a cross, but no one can say what he might be crossed with. Other than the ears, he looks like the other Aussi Cattle Dogs our family has had.

Anyway...was just curious! We got him from the shelter a few months ago an he's hands down the best dog we've ever had.
