OK, so some of you may know from previous posts that Osa got a knee injury and we had to keep her on a limited exercise schedule for a few weeks. That is now over so we are trying to up her exercise a little more. Yesterday we went for a 2 mile walk with the first mile being slow and the 2 a little faster. She did wonderful and didn't seem bothered at all. While we drove home she layed in the back seat and when we got home, her leg seemed stiff. She wasn't lame on it at all, it just seemed stiff. Is this some to really worry about and for those whose pets had injuries, did stiffness occur? The vet opens at 9 and I will give them a call but I just wanted to see if I could get any feedback here. The stiffness only last a couple of hours and after some laying around chewing, she seemed fine.
