Would you post a pic of the wonder dog? I need one like this!Dogs work for us. We have an aussie/border/lab/dunno mix that did a good job watching but is too much of a house pet. So, we got a Scotch Collie. Haven't lost a bird to predators since! He sits out there and keeps an eye on everything and kills rats, goes after foxes, goes after racoons, and has very successfully kept hawks away. I know his relatives will attack a hawk that gets close enough to the ground and I'm pretty darned sure he would too...but they've been smart enough to stay well away. We see them circling the field by our house and they won't come into the yard! Scotches are a good choice because they are low-maintenance for coats and health, fantastic pets, and by preference will want to sit and watch over the yard rather than be inside. If you can get a good appropriate dog breed, they are amazing...they'll even put the girls up if we need them penned so we can go somewhere without leaving them out!
