DeAnn Shepherd of the Humane Society of Utah told Fox 13 that this is the first time an animal has been left at the shelter with a list of handwritten instructions from a child. 
'It's the first time that a child has done this, and it was very heartbreaking to see from his perspective his relationship and friendship with this dog, but we hope that he sees the story and knows that his best friend is going to find a new home', Shepherd said.
