Always tough to lose a faithful friend, they always seem to find a way into our hearts and souls. Sorry for your loss and thanks for sharing Trigger's life with us and showing what a difference love and training can make with any dog.
Had to put my buddy down quite a while ago. One of the hardest things I've had to do, and still feels strange not to have him around.
Sounds to me that Trigger had a really decent life with you and yours!
Thanks for sharing the story and the pictures.
Condolences on your loss...
