I have a 9 year old Jack Russell, and she has always had a nervous piddling problem. It is worse if people talk to her in a babyish or high pitched voice. She is usually fine after things have settled down, and the guests have been here for about ten minutes. I have just gotten used to either putting her in another room for a few minutes when people come over, or letting her greet them outside as they walk up to the house--that way, if she pees, it's on the ground. Good luck. I haven't found any way to cure this problem.
