My GSD, 8-1/2 years old, is suddenly howling in her sleep every few days. She sleeps at the foot of the bed, and the first time she sat up and howled, laid back down, went to sleep.
Last night she sat up, howled - and howled and howled. I got up, turned on the light, and she was staring into the corner. I waved my hand in front of her eyes to break her concentration, she recognized me, laid back down, I stroked her head and she went back to sleep.
I swear she saw something I didn't see.
She's never done this before and howls very rarely - a couple of times a year, usually when a fire truck goes past my house (rarely, I'm in a rural area).
I'm worried about her. She is otherwise healthy, just had her 6 month checkup, is active as ever, sweet as ever, no other changes.
Anyone have any ideas?
