Our 18mo Border Collie is crate trained and has been excellent at going to bed and staying in bed since about 10 weeks. For the last 10 days or so she’s been waking between 1-3am and barking. I’ve let her out for a wee and then she’s gone back in her crate. I don’t think she actually needs a wee as she runs round the side of the house that I can’t see, and then reappears 20 seconds later…. Should I just leave her to ‘bark it out’? I think she’s playing me!
