If you haven't seen it, this is what the logo for my dog training business, Ruff Translation, looks like. (The background is yellow because that's straight from the webpage, which has a yellow background.)
I paid someone with an embroidery machine to make me a few patches with my logo on them. I just finished sewing them onto a new jacket for Dragon:
Now every time we go to the park or somewhere else to practice our training, he can advertise my services! The patches are open at the top so that they're actually pockets, held shut with blue velcro. Each pocket carries five business cards and two bright blue poop bags.
He's truly a working dog now.
