Animal control reminds me of the Witcher (which is going to be a TV series now on Netflix): an order devoted to fighting monsters.
If you think of the things that most plagued people in the past, they were things like disease, famine, fire. There would be a lot of money in businesses that addressed those concerns. You've already noted the fire departments. If magic were as ubiquitous as it is in say Shadow World, I can imagine Channeling casters hiring themselves out as healers and food/water summoners. The latter would be especially useful in sieges: a commander who had enough food/water summoners could hold out indefinitely against a blockade.
