This 158-pound hunk of teeth licks the guinea pigs until they're dripping wet, wags his entire back end at the sight of the cat, and lets 4-year-old strangers hug him around the neck and smooch him on the nose.
That's because he's been smothered with YOUR love and fed well too. He obviously isn't a fear biter(driven to be a neurotic mess). Most pets raised from pups are a direct reflection of their owners. I've seen over and over.
