It All Boils down to the dogs Vocal Chord
The vocal folds, also known commonly as vocal cords or voice reeds, are composed of twin in-folding of mucous membrane stretched horizontally, from back to front, across the larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation. When the dog barks, growls or whimper, the vocal cords tighten up and move closer together. Air from the lungs is forced between them and makes them vibrate, producing the sound. The strength of vocal chords is and air flow passage is mainly responsible for dogs having different bark sounds. (The larynx is also sometimes called the voice box. )
If for some reason you believe that your dog bark is off and not sounding as how your breed of dog bark should sound at it's given age. The best think to do is bring your animal to the vet and let him examine the dog's voice box. It could be a temporary situation as the dog having the flu which may affect his/her bark, or it could be an infection. If the dog's voice box has an infection, then the vet will make the appropriate actions to correct the dog's voice box and hence enhancing your dog's bark sound.
