I’m sorry you got attacked. More often than not, it’s the owner that is responsible for their dog’s conduct (and many don’t take into account that while said dog might be nice with them, it might not “play nice” with strangers).
I’m not a dog person, but this poor dog in the video was treated horribly by its original owner and essentially left for dead. He didn’t deserve that, and was able to be rescued and taken in by a loving family where he gets to happily run about in their interior yard.
Also, as some others pointed out, this may not be a pit bull breed.
Pit or not [still betting on Frenchy mix] NO animal deserves this.
Small wonder some dogs go bad, if this is the life they lead before they finally act out.
