nope, he looks like Andre the giant in my head only look cleaner and smarter. he gained his canine form when he use his NP.

well technically he's like berserker Jack, taking the rumor as his form but since he have a real human identity it become something like innocent monster,, the differences is Innocent Monster distort the original servant with some sort of physical attribute,  the case of this guy is turned completely to St. Christopher, his memory stay Mina but his temperament distorted into Christopher under the Mad Enchantment EX... He'll be 4 star Caster as Menas with utility close to Medea lily.
