This feels really inappropriate. You're a 15 minute old account claiming that the subject of the article abuses his dog. The appropriate time and place to air that grievance, if it actually happened, would have been to the police, when you witnessed it. It sounds like you're trying to assassinate his character otherwise.
If what's true? The complaint isn't even clear. And what does he deserve exactly, a lynch-mob?
I can't believe people have the audacity to write unsubstatiated claims of animal abuse about a blind person's guide dog on a post about their achievements as a developer.
