Does training dogs to detect narcotics and explosives fall under the prohibition against keeping dogs?

Question:
He says: Honorable Shaykh, may Allah grant you success, there is a job that involves training employees to use dogs to detect explosives and narcotics. His question is: Does the worker in this job fall under the ruling for the one who keeps a dog, according to the hadith?

Answer:
No, this is for a pressing need and dire necessity, so there is nothing wrong with it. This is like a hunting dog, a livestock dog, and a farm dog that guards the crops. This is even more important than guarding, as it is for the security of the people. So there is no harm in that, and no harm in training for it, because it is in the interest of the Muslims. Yes.
