re: Elderly dog barking at night, pacing, and seeming restless - any pet owners with advice?

Dealing with the same thing with my Shepard (16). Cries in the evening. Took him to the vet and they did a full blood panel. It came back perfect. His hips are weaker now and the cold weather isn’t helping any. I take him on short walks during the day. I tried gabapenten, but that made him so wonky the next day, he couldn’t stand up. Now we are trying melatonin with pretty decent results. Have tried cbd/Xanax/benydryll with the Melitonin and benidryll being the best combo so far. Hope to see some other reqs in this thread as I’m trying to let him have the most comfort possible in his older years.
