What do you call a wild dog that cannot bark?

This is a bit of a trick question!

Here's why:

* Wild dogs can bark: While some breeds of domesticated dogs have been bred to be silent, wild dogs like wolves, coyotes, and jackals all bark.

* "Barking" is a broad term: Dogs can communicate with a range of vocalizations, including growls, howls, whines, and yelps.

So, there isn't a specific term for a wild dog that can't bark because they all do!
