Macomb County Michigan : Health Department: animal
Because buying, selling and breeding dogs (of whatever size) is not illegal, I doubt it will do a bit of good. If she does have a kennel, there are certain laws that have to be followed but it isn't too hard and the penality isn't nearly enough anyway.
Any animal sent to AC in Macomb may be rehomed or euthanized at the discretion of the staff.
