Best wishes to Brad for a speedy and full recovery. I know how bad a fall can be. Last October I put my foot down the wrong way and ended up with two sprained ankles, strained quad muscles in both legs, and a pulled quad tendon; all from one innocent misstep. I'm almost fully recovered, but in the process of recovery I gained six pounds that I had formerly worked so hard to take off.
I will say this, however: nothing speeds recovery like a beautiful and faithful Sheltie!
