Lost Dog Basenji ???

I live in the Mt Baker area and there has been a lost dog in the neighborhood for about a week now.  It has a purple collar and is brown and white.  No one has been able to get near it.  It is hanging around the Cascadia, Mioposto area.  Anyone recognize it?  Looks like the picture but darker brown.

Gang Tags

I know there is a website that lists the gangs in Seattle but does anyone know which TAG corresponds to which gang?  Is there a listing someplace?
