I hope this is the right spot to post this... I've been reading a lot of posts about Guardian dogs. I'm considering getting one. We live in VA (I'd say mostly 20s in winter at night). Is it safe to leave the guard dogs outside when it's that cold? We have 2 dogs (blonde lab & shi-tsu mutt), but they're pampered indoor dogs. I thought if we got one for strictly outside it might be nice. Our neighbors have a Great Pyranese (not sure if I spelled that right) but he barks allllllll the time and I find that really annoying. I would LOVE to have a herder border collie. What do you suggest? Is there a good breed that would not bark at people, only predators? As always, thanks for your wonderful advice!
