Here's another paranoid doggie mom. I've never left my
dogs outside all day either. There are too many variables when
outdoors. If I worked at home, I leave Smokey out longer, but
I want to be able to see him every once in a while. I always
thought a barking dog could do little to deter burglers if they
were confined to the backyard. I also agree with demigodess
in that a lot of things depend on your dog's temperments. Some
might be fine outdoors & some not. Good luck with your choice.
