The situation is by far not as clear as you would suggest here. The dopamine gene for example was shown to have no effect on neurochemistry in mice [1]. Even on the surface, there's a lot more to possible Toxo induced behaviour changes than just dopamine, as evidenced by neuroinflammation or cysts in the amygdala. Noone has figured out how these things actually work so far. And diminished fear response to smells in mice is a long way from general entrepreneurialism in wolves.
