Actually, The Dogs of Heaven are the complete opposite to the Order of St. Michael in every way possible except for the fact that they are apart of the Catholic Church. Chloe is affiliated with the Order of St. Michael and she doesn't exactly like any of the members of the Dogs of Heaven.

Basically everyone is their enemy as the infobox states: "Kill all those who are declared the enemies of the church in general and Exterminate all that is "unholy""

So they quite literally fight everyone in their way of achieving their ultimate goal.
