David,
I am glad to hear from you again, wondered how you and your wife were doing. Glad she is doing better and hope the back can be healed completely. I well know what a long, painful road a back injury can be. Good to hear the puppy is working out well, I hurt bad when I read your original post about the lab being put down, we have had to do this a few times and it hurts worse every time.
Prayers for you and your wife that she can return to riding soon without any pain.
Bill
