What Makes A Dog Howl At Sirens. When one wolf howls he will reveal his location. Based on their behavior when they howl at sirens this is the most likely explanation for the phenomenon. Dogs start to howl sirens because they realise the sounds are not theirs. When a dog howls at a siren the most likely reason is that the sound is so close in pitch to a community howl that the dog thinks the siren is a long-lost relative.
The sound is new and new often means dangerous in survival situations. Dogs ancestor is the wolf and howling was one of the main ways of communicating. The dog is a social and gregarious animal which always tries to communicate with its pack including its human. The third reason a dog can howl is that the sound has triggered the animals instincts. The sirens traveling on the same exact airwaves and frequencies trigger the dog to howl to establish the territory they are in ergo the property they live in in efforts to keep intruders out. Bringing the noise to your attention and verbally scaring the sound away.
Dogs howl at sirens for the simple fact that dogs are animals that are prone to vocalizing in response to certain sounds.
Yet another explanation for why dogs howl at sirens is that they simply enjoy the sound and want to join in. Again dogs howl even when someone plays the piano or howls at their dog but its the internal communication while stimuli from out-of-pack-and-territory triggers territorial boundary indicating communication. Howling in domestic dogs isnt a well-researched field. To communicate the dog basically uses body posture and vocalizations. Another wolf will do the same thing for the same reason. Understanding this behavior requires taking a closer look into a dogs genetic past.
