She is now 21 weeks - things going ok. She goes in her crate at night, when she wakes up she barks (this is at a reasonable hour of 6.15 - 6.30). i get out of bed to let her out - but obviously need to go to toilet etc and she continues barking (as she can hear me). I only let her out when she is quiet. Any tips on how to stop this barking? Am I too late?
