there are no words for when we lose the ones we love and its compounded when we feel guilt ... you have no reason to feel guilt.. both you and the vet agreed it might help her and prolong her life... but it wasnt in the cards,, there are things in life we have no control over and this was one. You gave her the best life and she looks so happy in the pic you sent us... she knew you were there and I am positive she felt nothing but love and took comfort in knowing you were by her side....
Please feel better soon...

Rest easy and play hard at the Bridge!
