Why do dogs howl all the sudden?

Question

Why do dogs howl all the sudden?

Answer 1

They howl because they can hear things, that the normal human ear cant.

So, when it's quiet outside, and you dont hear anything, your dog could be hearing a firetruck, or another dog howling/barking.

I actually think its quite cute. :]

Answer 2

Howling is a form of communication in dogs. It is a way for dogs to signal their presence to other dogs that are often located far away. It is common in wolves and coyotes, both relatives of today's domestic dog.

Domestic dogs that howl, especially those that howl excessively are usually doing this because they are bored and lonely. Getting extra toys, and giving your dog more attention and exercise will help to stimulate your dog and reduce excessive howling. If you make your dog sleep outside all night, it's no wonder the dog howls a lot. Bring the dog inside!

Sometimes dogs will howl when they hear sirens or other loud higher pitched sounds like clarinets and flutes. These sounds may even come from a television set. Dogs do this as an instinctive response to hearing what they interpret to be another howl (dog in the distance). They are not doing this because it hurts their ears.
