I'm dog sitting for my brother for the weekend. It's an old Pembroke welsh corgi. I'm not exactly sure how old. Anyway, it's really late at night, and he's been whining. I have no idea why. I fed him and I took him out already. I stroked and petted him a lot too. Why is he whining? Could it be that he misses his owner? What do I do about this? How do I get him to stop?
