10 weeks with Atlas - I got him when still living with Mum and Dad, they had an older dog that Atlas annoyed the crap out of - so he was crated when I was at work, and out when I was home, I moved out a few weeks later and Atlas had run of the yard while I was not home.
When I got Kaos i kept her crated for a few days, till I was sure she and Atlas were ok together, then put her outside (she hated being crated)
Any future pups will be outside as soon as I get them, unless there is a reason for them not to be!!
Mine are mostly inside when I am home, and out when I am out (well, not today, i just mowed the lawns and have 2 green dogs, they are both staying outside!!!)
