Chocolate is literally poison, period. Seriously, it is. The lethal dose is just really high for an animal the size of a human, but for a dog.. Yes, killing a dog with chocolate treats is absolutely possible (think I heard on QI that something like a smartie is enough to kill a small songbird?). Animal abuse, criminal neglect, whatever. Nail this fat piece of shit. She can fuck up her life as much as she wants but now she's taken responsibility of another life, and failing in her duties. Fuck, that makes me mad.
