Trying to work out what is wrong (if anything!) with my dog. He's a nearly 9 year old cockapoo who's always slept happily in the lounge/kitchen/dining room. For the last few weeks he's cried/barked for hours at night and I have no idea why. If I get up he will lie down next to me and be snoring in minutes. I've spent a few nights on the sofa but I refuse to have him in my bedroom as I am too light a sleeper. In the day he's normal - running around, long walks, chasing squirrels, eating and pooing normally. Any suggestions?
