It's very unusal indeed!!
If you look at the hind quarters and legs they are much thicker than a dog or wolf. It resembles the thickess and shape of a lion (female one).
The head does indeed look a little too small for the rest of the body.
It looks like a cross breed between the dog and big cat families.
It also looks freaky too especially with that hair do!
Isn't there any Zoologists that can confirm what animal this is? regardless of whether this is suffering from Mange.
P.S.
Here's a pic of a Coyote:

Notice the difference?
