My Sheltie is only 2 1/2 years old. As far as I can tell he is a healthy dog. However, it has come to my attention that he has been having what I think are leg spasms. The spasms are just one kicking motion always in one of the hind legs. When I first saw it I thought he was just stretching or had an itch. However, one night he was laying in between my legs and all of a sudden one of his legs spasmed, the kick was hard enough to leave a bruise on my thigh the next day. The fact that he was practically asleep at the time made me realize the movement was involuntary. Then, on accident, I came across some information saying that Shelties sometimes have leg problems. Should I be worried? Or, is this just from running around too much that day or something and is a normal occurrence for Shelties? The "spasms" aren't exactly frequent (I would say I witness at most 3 or 4 a week). Thanks in advance.
