Razor Face

What if Razorface is a homeless dog?

• He wanders around, comes back from time to time, looking for a place to get comfortable and rest;
• is getting old, maybe blind now;
• his 'people' disappeared and left him so he can't go home (happens more than you'd think);
• doesn't understand the world of people but lives in cities ('must be hard for the likes of you to get by in a world that you just can't see through);
• Maybe an 'aging star' knows of him and sings about him.

Just a thought
