we just finished mochi's crate to bed transition. we crated her every night beside our bed and whenever we went out. she had just turned 8 months old when we started to test her out of the crate. she had been accident free in the home for about 2 months, so we thought we'd give it a go.
first night, didn't put the crate away, but she settled down nicely in her dog bed at the foot of our bed. she got up in the middle of the night and started barking. not sure why, she probably heard something that spooked her. so we immediately put her back in her crate for the rest of the night. 2nd night, same thing happened, so she was put back into the crate.
3rd night she was fine so she slept on her dog bed the entire evening and we have had no more waking in the middle of the night since. no accidents in the bedroom. after a couple of weeks, we decided to let her stay in our bedroom (behind the dog gate) while we went out for a couple of hours. mind you, the crate is still in the room, but she never goes in on her own. each time we'd test her out by leaving for a longer duration. now after a week of that and no accidents, we finally put her crate away! whole process took almost a month, but she's very happy in her doggy bed now
oh and luckily, no unwanted chewing behavior either!
P.S. your pup is still so young. wait until the teething is completely done and over with!
