Just asked the BF if they are trained on how to treat dogs in the academy. He said they just spent three days on family violence from 8am-5pm. Next three days deal with child molestors and the next week is spent on how to not get killed (safety precautions, how to enter homes, how to calm someone down). He said dogs are not a priority in the academy, they are learning how to save human lives instead and stay alive themselves. They did get to see some cool drug dogs though, and the k9 officers are revered there. He said the professor said that if they want to learn about dogs than to join animal control. And he said he is not asking any more questions for me since the prof made him look like an idiot for that one lol
