Jake's limping again too. I really think it's the weather. He hurt his knee this summer. I know my knee (which was injured in the past) hurts more lately too, and so does my husband's ankle. Maybe all the new limping is due to the change in seasons. I was thinking of giving Jake some of that pain medication the vet gave him, because I have some left over. Maybe on really cool, damp days I'll give him some first thing in the morning.
