"This is the face of a mum who has seen her son experience countless failed social interactions on the playground in an attempt to have a friend. Any friend. Any kind of connection.
"She has sat with her son while he has cried at night for months because he has no consistent connections outside of the family no matter how hard he tries and no matter what he works hard on in his autism therapies. It doesn't transfer to the natural occurring world for him. And now she is sitting behind her son silently watching this moment, with the air sucked from her lungs, and no words to say."
She added: "It's worth every fight for services for my son, every diagnosis, every new provider, every dollar spent, every paper filled out, every school meeting, every shed tear, every step forward, every step back, and every wonder of the unknown future. Somehow because of this - because of Tornado - I know everything will be okay.
I'm not sure why, but people still ask us why we place service dogs with children sometimes. Let me help you...

"As a mother, I have seen countless challenging and painful moments my son has encountered and cried countless more. Yesterday however, I cried for a different reason. It is a feeling that is indescribable."
The photo has been shared by more than 15,000 people, with 4 Paws For Ability adding they were "touched and elated" by the response.
Earlier this year, this smiling dog almost lost his new home after an adoption selfie alerted police.
While these loyal dogs also won internet praise after refusing to leave side of dying baby girl at hospital.
