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

I was talking to a friend about this thread, as he recently had to put his dog down and the situation sounded similar. She did have a UTI diagnosed, but it resolved and the strange actions at night did not. He tried a sedative, but it got worse pretty rapidly and he did not want to see her suffer with the confusion and anxiety. I am sorry you have this going on.
