Three hours might be her max limit. I was a bit over last night and there was an in crate accident. I got the ebook from
The Housebreaking Bible and there was a suggestion to sleep for a couple of nights with your pup in their location.
It was such a simple idea I can't believe I did not think of it before especially as her crate is already beside the couch. . So I might be "in the doghouse" so to say sleeping on the couch tonight.
