Some common methods of training used for working animals like guide dogs or police horses include positive reinforcement, clicker training, obedience training, and behavior shaping. Positive reinforcement involves rewarding desired behaviors with treats or praise to encourage the animal to repeat those behaviors. Clicker training uses a clicker to mark desired behaviors and then rewards the animal with treats. Obedience training focuses on teaching the animal basic commands and manners. Behavior shaping involves breaking down complex behaviors into smaller steps and teaching them gradually. These methods are effective in training working animals to perform specific tasks and duties.
