Hello, my 8yr old dog had the knew surgery in 10/2014 on her left rear leg, but with a little running & playing we started to do a couple of months ago, she will limp on that leg after resting & this lasts from a couple of days to a week - I thought her leg problem would've been solved with the surgery but it doesn't appear so, the vet said she could have a torn meniscus, does this mean more surgery? I would like to avoid it - it's hard on her but probably more so on me, not to mention expensive even with Pet Insurance & what if it doesn't work & she injures it again? Thankyou :)!
