oh that was a long title 
anyway we have had jaydog for months and he is starting to bark at 4 am it has been 3 times this week for a while I leave him as it is a low bark but he gets louder, He gets out at 10'30/11 and usually is out again at 7/8 . I dont know what to do I have to get up to him as we live in a flat and dont want to disturb neighbours, I am very very tired as it takes a while to settle him down again and some times he needs to pee so I am out at daft o clock, what could be wrong with him and what do I do, he doesn't seem ill and he sleeps in a crate he came from rescue crate trained,
