And yet another vote for Cholodin, it helped my senior with canine cognitive disorder through her last couple years with less anxiety. It did improve her symptoms of restlessness at night and pacing aimlessly, it also lessened her whining somewhat. It wasn't a cure all, but when I tried taking her off it (during a time when she was having a bizarre skin reaction & we were trying to figure out the cause) she got significantly worse.
It's definitely worth trying and is not a prescription med. but a natural supplement.
