I'm anti leave the dog out unattended also. My choice. If mine are out, I wont even run to my moms house for a sec (1 mile down the street) they either get brought in, or I dont go. We live i the sticks, no real concern for theft, an occasional curious passerby has pulled in to see them though. They have kiddie pools in each section, fresh water, shade, etc....but never never unattended. I like to make my pens as escape proof as possible, but taking no chances here! Barking isnt a prob since the closest neighbors cant hear them anyway.
They have access to their rooms in the basement and the backdoor is open for them to access the kennel. My basement is underground so even in the dead of summer its still around 65 degrees in the dog room. I also live on a mountain on ten acres of land.
