My dog is nearing 14, and at times he likes to get up, stretch and turn around, but he started wandering if he did that during the night. When I'd turn a light on, he'd come right back and lie down next to the bed or crawl in with me again depending on his mood. I wondered if it was the dark so left a night light on, and yep, that did it for us, too. As our dogs live longer, they will have more cognitive issues just like old humans.
Night Lights for Aging Dogs
A tip for your aging pet section. My 13 year old g. shephard mutt started to lose his eyesight and hearing recently. This in turn caused him to be disoriented at night -- with a hint of dementia! As soon as I got into bed and turned off the light, my dog would get up from his bed (at the base of my bed) and wander around the house looking for me. Well, one night he tripped down the stairs because it was so dark. Enough was enough. The next day I went to Home Depot and purchased 2 nightlights, one for the hallway and one for the bottom of the stairs. Now there is enough light peaking into the bedroom that he no longer gets up disoriented. Hope this helps someone! GS.
P.S. I really liked your comment about the hard wood floors and aging dogs. I totally agree.
