I am so sorry for your loss. Jack was a beautiful boy! There is a lot of depth in those eyes! I admire you for choosing to not let him suffer longer...a hard choice but the right one. Peace to you. I hope he is now running and barking freely somewhere out there in a new realm. Universal speed to Jack
