Aren’t these usually ultimately, a mangey coyote with severe loss of fur?
That’s what they want you to believe.
Or outright hoax.
I rescued an abandoned border collie mix that looked like that before her hair grew back. It isn’t always mange but a natural mite will cause hair loss when a mammal is malnourished. This was probably some poor dog looking for food.
