Hi all, I have a 9 week old Labrador puppy. Once tired out he takes very well to his crate, however we haven’t successfully made it an entire night with him sleeping there. We worked really hard over the course of the week with this and last night was going to be the night. He made it until 4am when he needed to go out to pee, and when we came back in and he went back into his crate with the door latched shut, he began chewing on the metal bars and got his teeth caught with his mouth open. He panicked, which resulted in me trying to sooth him and unlatch his teeth. Luckily I think the only one slightly injured was me, but during my “I’m a horrible dog mom” meltdown I was too scared to relatch the crate door as he continued to chew on it afterwards. I work three days a week, one of those he has a puppy sitter but as of this week I was planning on keeping him crated for 4 hours each of the days with a potty break by one of my roommates. Now I’m afraid he will hurt himself if left unsupervised. Any advice or constructive criticism is welcome - please help.
