Please, please, please, Cindy... NEVER, EVER feel guilty about Gavin. No one could have or would have done as much as you have for him. As long as I have been on this forum, I can count on one hand the people who have gone above and beyond for their Shelties. You are on the top of that list! You have my undying admiration for the love and devotion from Gavin's radiation treatment when he was first diagnosed until the new brace! You are the light in his life! Virtual hugs to you both!
