Why is Blue Dog Blue?

This is a photo of me in George Rodrigue's gallery in New Orleans. We went to New Orleans last year during Mardi Gras. Our hotel was on the same street as Rodrigue's gallery (Royale Street.) I LOVE Rodrigue's artwork; when I was student teaching, my cooperating teacher, Carol, had Blue Dog hung all over the classroom. Her love of Rodrigue's art really inspired me; now I have my own Blue Dogs hanging in my classroom. My students love him!
