Well, not the ACTUAL loo, obviously!! But I was wondering at what age their bladder/ bowel can cope with not needing to go to the loo in the middle of the night? I'm asking, because I DO have a crate for my Lakey, but I haven't actually shut him in yet - I had done so when we first got him, but it was a bit of a nightmare. I DO NOT cope well with sleep deprivation!! I think he's asleep until about 5am now, with no messes until about then. I can cope with 5am (it's when ds2 wakes up for the day -grrrr- and I think he disturbs the pup, hence the mess!).
Or is it a case of when an individual pup is ready?!!! To be honest, I think I already know what you're all going to say, but it can't hurt to ask!!
