K9s can come and find people when a disaster strikes. When a huge storm happens and people are trapped in a building or are just missing dogs can smell something of theres and can find the scent on the ground. They can also go in deep spaces and small spaces where we can't go. They can smell out bombs and can track down people on the run.
Every day, K9s do miraculous things. K9s are a great asset to a team, they can fit it tight and small spaces. They can smell things from up to 40 feet. And attack some one who fled from the crime scene. The most preferred dog for a K9 unit is the German Shepherd. They have a great nose and have sharp teeth for taking people down. They can listen to commands given at any point in action.
The CIA likes to have K9 unit at a scene because they can find things that us humans can not. One thing that they like is that all dogs are not trained for the same thing. One dong may be trained for looking and smelling for bombs and another might be trained for helping people and having supplies for people on there dog packs. Dog packs are a vest around the dog's upper and under belly and it can have supplies for his partner or it can have tools for fixing or tking things down, it really depends what's happening in the
