This is a champion Neopolitan Mastiff in India, and the worst looking dog I have ever seen.
It is important to note Neopolitan Mastiffs are very rare breeds, and are outliers in the dog world in the way that circus freaks are outliers in the human world. Of course, even in the world of circus freaks, there are some freaks that are more shocking than others, and this Neo falls into that folder. This dog's death will be a relief to itself. If it could load the gun and pull the trigger, I have no doubt that it would.
How did this dog come about? It was, as is the case with so many dog breeds, a conflux of pretender and pretension, avarice and ego, with defomity, disease and dysfunction held together with the glue of delusion and denial. I tell the complete story here.
