Those were created by a member on BYC - they were also featured on Animal planet. The show about Best Groomer or something. She used dye that washes out or Kool-aid or something. I think they are kind of cool since the dogs weren't harmed in any way.
i dont remember who it was but i remember telling her how talented she was on here...it was right after i joined. i cant remember the name of the thread though.
