His name is Calvin. He's a anthropomorphic dog who is 19. He is more of a playful person than most other people, while he can be respectful and kind at times, this dosen't mean you can annoy him everytime, as he will get annoyed by it. If you push his limits too much however, he'll act like a hostile dog who barks at almost everyone who gets any closer. Fortunately it's pretty short-lived as he'll be in his normal state after around 5-15 seconds of his fury, alebit still being angry or annoyed. He's netual-friendly, if you fist-bump or do a high-five with him, he'll be happy.
