bongo dog mural, se pine

And then there's this mural of a cartoon dog playing bongo drums, on the back of a building on SE Pine between 9th & Sandy. I don't know anything about this one; it's not signed, and searching the interwebs about it comes up with precisely nothing. It's on the back wall of a commercial printing company, not a veterinarian or dog day care or anything, so the business isn't an obvious clue either. There's bound to be a weird and funny story behind this, but I have no idea what it is. If you know, or you have a theory about it, feel free to leave a note down in the comments. Thx. Mgmt.
