Bulldogs World

I had posted on here earlier about my 7 year old bulldog having arthritis in the two front elbows.  But now I am questioning if it might be something else.  The x-rays did show arthritis, but the vet said it was minor.  She has been limping for about a month and had a few good days without limping.  We took her to her first acupuncture this past Friday (along with meds and supplements).  I started reading about dog arthritis and it sounds like it is not something that comes on sudden, like in her case.  She started limping after chasing a deer.  The deer was outside our fence and I guess she thought she could catch it.  My question is has anyone else had their bulldog get arthritis really quick like this?  I am not questioning that she has it, but if that is really why she is still limping.  I just feel so bad watching her try and get around.
