DeathByPuppy We'd had a pupply previously, albeit 12 years ago, so we'd should've been prepared, but you forget how much hard work they are
It will get easier, I promise 
You've just got to get through the peeing, pooping, crying, biting, etc., to get there. Biteypup is by no means perfect, but she's a million times better than she was several months ago 
I still have days where I wonder what the hell we've done, but I also felt like that 12 years ago with the last pup and he turned into an amazing dog that I still struggle to get through life without
