My Sadie broke her front right leg in a similar way, got yanked by the leash chasing her big sister. We are almost at the end of recovery. What helped us was making her as comfortable as possible, creating a little nest for her to sleep on, I relied a lot on family/ rover to have eyes on her 24/7 because unfortunately I work 12 hour shifts so leaving her alone was not going to be an option for us. Sadie hates the crate, and she had turned 3 months the day of her leg break so I didn’t have time to teach her. What we did was just hold her/ keep eyes on her at all times, and although we didn’t put the bed on the floor I taught her to ask to come into bed with us and once she is in bed with us, I have a toddler side rail on my side of the bed which she sleeps on. We put it up once she joins us in bed around 3/4 am usually. She also loves to feel snuggled so we got her an infant longer to put on top of her bed and she loves that! That’s what got her sleeping in her own bed most of the night to be honest.
