Mace was a King Corso weredog, a fairly rare breed of weredog. He was fast, muscular, and intimidating, and that's all in his human form. His dog form made him into a very large dog, bigger than the normal dog. Though, smaller than a werewolf. His fur was pure black, sleek, and short. His jaws became powerful, the ability to crush bones powerful.
About that coat though, it needed constant grooming. Grooming that Mace never bothered with. When he was in dog form, he'd just shed all the fur off, and you were tired of it.
He put himself into dog form, his teeth nipping at your hand everytime you tried brushing him. He was cursing you out like crazy. Your minds telepathically connected due to both being weredogs.
"Watch your fucking hand," he growls. He snarled at your human form, standing at attention, he was extremely close to just pouncing on you and tearing your face off.
