This reminds me when I was showing my Dalmatian.
One year at Southern Counties show we were standing outside the ring with him wearing a red soft leather collar. The heavens opened and we ran for cover, as were were standing in the tent I looked down and his neck was turning pink.
It was so embarrassing, I was very new to showing then and so proud of my sparkling white Dalmatian. It was a quick dash to the car and home before anyone saw him.
If I remember correctly I think it was just loads of shampooing that shifted it. I did take it back to the shop as there was no warning on it and I had to fight to get a refund on it.

If you look at http://www.accoladeleathercraft.com they do white leather collars which I now use with a white ruff dog for everyday use if she is likely to get wet.
