To top it off, it is fair to say that there are actually many Siberian
Huskies (and the very closely-related Seppala Siberian Sled Dog, from
which the modern-day Siberian Husky breed was developed) which are
called "mostly black", which have variations in black and white like
this (and like the original, real Balto). To wit:
Well, Star Fire, black and white markings are fairly common in dogs.
XD Other than happening to share a :very common: color scheme, this
dog is pretty distinct from real!Balto.
