When a puppy is young, the earlier they begin their training, the better. The type of training that these dogs will have to do depends on what breed of dog they are and what job they will be performing.
German Shepherds and Malinois are best at protection and patrol dogs. Labs and Bloodhounds make great scent dogs. Beagles are great at working in airports and border patrol.
Usually, this training may begin around eight weeks of age. They will have to start to learn basic obedience training and start socializing with other people and animals. These dogs will start to learn to sit, stay, and come. These dogs must master all these commands both on and off the leash.
Once basics are established, the dog will begin training for basic tasks that they are going to be assigned. While learning their task is important, they must be socialized and ready to focus. Many times, they are being trained to obey commands while having to intermingle with people and other dogs
Many police departments purchase a dog that has already been trained. All they will have to do is to learn the commands from their new handler. Even though a dog has been trained to do their task, their training never stops. These dogs are constantly in training when not at work so that they are ready for whenever the time comes that they are needed to save a life.
