Shasta couldn't be trusted to sleep out of her crate until she was about 9 months old. We tried it a couple times until that point and she always got into trouble. She's almost 3 and has only recently started being home uncrated when we leave the house for short periods of time. Some dogs can be left uncrated from the start with no issues while others cant. It just depends on the dog.
