My approx 3 year old female was playing football in the snow a couple weeks ago and ran back to me limping, the vet said it is a torn anterior cruciate ligament (ACL). He said that surgery could bring her back to 95% recovery. He also said that before surgery I could try walking her 5 to 6 miles.....A DAY!!! (I love my dog but do not have that much time....or energy). Has anyone had success with any treatments to strengthen the other ligaments (ie. walking) as opposed to the $1,800 surgery?
