We'd really like the logo to look like a sports organization or team logo, since that's what athletic directors will relate to. Think NFL, NBA, MLB, etc. Red, white & blue, possibly stars, the feeling of action, energy, power, motion, entertainment. It's fine to incorporate a dog into the logo, too (but not a requirement).
We need a color logo for the header of our website (and biz cards, etc.) but will also be hot stamping it onto frisbees. For the frisbees we need a 300 dpi version that will fit inside a 5-inch circle, black & white only (no grayscale or colors).
