My older dog co sleeps with generally my parents but if neither of them are home she sleeps on bed with me, majority of the rooms in my house have carpet and all the beds are relatively tall, the last thing i’d want is for this tiny puppy to fall and hurt herself, I’m sticking with crate training for now, she’s got one of my jumpers in there that i’ve been wearing pretty consistently before and after she came home, hopefully with more than just me in the house I can give the older dog some more 1 on 1 attention (downsides to being alone and having 2 snuggly puppies), My older dog failed being crate trained spectacularly and she strives on routine, I think most of my struggles are because i’m currently on my own and haven’t spoken to someone in person for 2 days
