tremors

Question
My 11 year old female broken coat jack has been developing a shake for some years.  She was hit on the hip by a car when she was 3, but I can't say I really noticed the shaking until a few years ago and it is more pronounced now.  Everyone thinks she is cold.  The vet isn't sure what causes it.  She is not on medication.  Any idea what it might be?  She does not seem to be bothered by it but I wonder how much worse it might get.

Answer
Hi Deborah,
I know it looks heartbreaking and you just want to wrap them up, but basically the shaking is just a JRT trait. Does she stop shaking when you pick her up and hold her tight? I found that works well with the ones that really shake up a storm. Just keep her comfortable and make sure she's not cold for real, but basically, they just do. Sorry, not so much of a help here but there's no real definitive answer.
She's 11, great job with her!
