We rehomed 2 Bichons 3 weeks ago, both adults (5 & 7). They were very clearly well loved and cherished in their previous home, but not looked after properly - they'd never been to the vet and they had no training. Except they are house trained and always ask to go out in to the garden when they need to go. They are doing really well with us and have learned to respond consistently to commands such as 'sit' and 'get in your bed' and most importantly 'no'! Problem: Toileting at night. They sleep in our room in their own beds, but tend to get up in the night and toilet either in the bathroom or at the bottom of the stairs. It's almost every night. We can always tell which it was because when we point it out one of them shies away from us. We point and say a stern "No!" and the message gets through, whoever it was will hang their head and skulk off for a while. We put them out at night before bed and wait for them both to go toilet, and give them lots of praise as they do (it's embarrassing 11 o'clock at night out in the garden squealing "yeeeeeah, Elsie did wee wee's!"!!) ... what else can we do!? How do we stop it? My only idea is to set my alarm and take them to the garden at 2am but that's not practical, how do you teach a dog how to hold it, they've obviously not learned to!
