Well, it's my understanding, that most good dogs, with a little patience and training, will soon learn some routine, including what a safe kennel/cage place is, similarly as learning that a mat/bed in a "favorite" spot is a limit to their wanderings.
I once had a golden retriever and black lab and would bring them inside when it got cold and/or on other occassions. They quickly learned their places and limits, when inside. I've seen this with other dogss, as well, so I would expect Kaci to become just as obedient.... after all, she's in good hands.
Speaking of building, but not a cage for indoors, I made this dog house for a friend's shelter dog, that also quickly learned her places and limits when inside:
There's been a little chewing on the posts, but I don't mind going visit and repair these.
I'll vote: Kaci and Dave got/will have the best of the adoption deal, all round!
