Agility causes my dogs hair to change color?

Well I guess that caught your attention.
My saint has nice WHITE hair on her back but after doing tunnelers it is gray.
So nice clean tunnels for the dogs that follow her.
But it was worth it to get her 5th Q in novice tunnels
Thanks too the judges and workers who did a great job.

AH-HA! Thanks for solving the mystery of my black dog's gray hair! It's agility's fault! It just took a few *years* instead of a weekend...<BG> Maybe that's what happened to *my* hair, too....?

I need a few "tunnel cleaners" to come run through my tunnel please!  Will gladly pay car wash prices!
