This is Cassius. He's a dog.
My main fursona and currently only character I have a fursuit of.
He has gone through some design changes, he used to be a wolf.
Then became half GSD. Then full GSD.
He has new facial markings, I have since added them to my suit.
For easier ref for his facial mask look at these gsheps:
