11 yr old Corgi. Has been whining on and off at night for a few months, but just recently (the last week or so) has started whining constantly. He'll whine a bit then it will turn into a bark. He seems like himself except for the panting. It's like he just wants to go outside all the time. He's been hungrier than before. He had his thyroid checked a few months ago, that was normal. He just got over a neck injury, but isn't limping anylonger or acting the same as he did when he was injured.

I'm lost. I'm not getting any sleep.

Any ideas?
