I too have an outside dog... 24/7... I huge and I mean HUGE lab... He is 108 lbs. He wouldn't even want to be inside. Is he chained. HELL NO!! He has free run of my yard.. The kids go out with him and so does Daisy. I don't think that makes me a bad person. It doesn't mean that I love him any less. He's just an outdoor dog. I might get scolded here, but I don't see anything wrong with it. He has a fabulous dog house with a shingled roof that my hubby built to boot..
Edit to say that my yorkies do not and will not ever live outside. Yorkies are not meant for the outside.
