WATCH: Dog calms down owner with Asperger's during self-harm meltdown

This is a tough watch but what this dog does is amazing.

Danielle Jacobs has Asperger's syndrome and suffers from depressive meltdowns and panic attacks.

Her service dog, Samson, is trained to stop his owner’s self-harming episodes and Jacobs set up a camera to record one of the more recent ones.
