Why Do Dogs Bark When They Hear Sirens. Your dog feels like something is unusual is going on so your dog is actually trying to warn you that something bad might be happening. This kind of howling is. While dogs bark in a low pitch their howling is quite high-pitched. There are certain sounds that can trigger howling in your dog for example many dogs howl when they hear sirens.
Sirens are also high-pitched so when dogs hear them they may interpret those sounds to be the howling of another dog. Another reason that dogs might howl at sirens is precise because they dont understand what they are hearing. If Fidos howls are frequent and bothersome desensitize your pooch to this sound with training. They tend to perk up their ears and wiggle their ears to find the direction of the sound. In fact yipping and yowling is one of the ways that packs of dogs will communicate excitement to one another. That is the dog thinks he is communicating with another dog.
This new sound may be harmless but it may also be a threat and as they say its better to be safe than sorry.
If your dog howls at a loud sound it might be to get your attention. Typically when a dog is in pain they attempt to flee or display several other signs of injury and fear. So when some big crazy unexpected event happenslike say a screechy siren your dog springs into duty to alert the Alpha. The dogs are reacting to each others barks. A common trigger is the noise of a fire engines siren blaring within hearing distance of your pooch. I liken it to people in a bar or other crowded place.
