What is "Mutt 'n' Vair"?
The logo comes from my activities in my history club. The emblem is unique to me, as checked and registered by a battery of experts. If you want the formal description, it's "Vert, a mastiff salient argent and a chief vair". (Green background, featuring a silver/white leaping mastiff dog and top section in the blue and white interlocking bullet (vair) pattern.)
It follows the rules for good logo design, so why not use it?
