Toy Wolves?

 ...they might be known as "coyotes."

A gene that controls body size has been found in every single species of canid. This gene is one of the factors we've bred for to create your terrier. Or toy poodle. Or chihuahua.

But in a lesser form, it distinguishes between large canines (wolves) and smaller ones such as coyotes, jackals and African hunting dogs.

So a coyote is a toy wolf. Or at least a miniature one.

Arf!
