Smelling, Seeing, Hearing

Dogs have very good senses. They have an excellent sense of smell which has made dogs good at tracking as well as sniffing out illegal items like drugs or bombs. Some dogs are specifically bred to increase their sense of smell. Dogs also have an excellent field of vision allowing them to see almost in a complete circle. Their hearing is very sensitive as well and has a large frequency range. This enables dogs to hear sounds that are much higher than humans. Their great hearing makes them good guard dogs.
