There are certain things that most dogs are able to do automatically and by instinct. For example, could you ever imagine a dog that was not able to howl? It seems to be an ability that any dog is able to master but it appears that this dog is having a difficulty. Fortunately, he has a loving family that is willing to lend a helping hand and you will love it!
A dog may howl for a number of different reasons. In some cases, it is to organize the pack or to mark the boundaries. It may also be a matter of anxiety or due to injury. In any case, it is a unique sound that can be quite beautiful (and frightening) on a dark night.
