|I really hate when people post on these forums and say "I don't know", but... I remember years ago there was a problem with Eukanuba dog food causing lack of pigment, not only that but also causing black coats to "rust". Turns out, the problem was a lack of zinc in the food.
I have also heard about other cases where zinc has been found to help with pigment issues. I know my yellow labs lost pigment during the Winter, not just on their noses which is typical in many breeds, but they also lost it on eye rims and foot pads. Many breeders swore by zinc, but I'm not sure it did much, HOWEVER, that was a pigment loss due to either cold OR decreased sunlight. In my thinking, that might even be a lack of vitamin D??? Especially since most of the vitamin D our dogs get is from sunshine.
I know adding zinc has to be done carefully since it is not water soluble, excess ends up in the liver I believe?
I really don't know, but I think it may be worth a good google search for zinc and/or Vitamin D deficiency?????
edited to add: I just went to look at your page and noticed all the snow. Has this pigment loss only begun with the beginning of Winter??? If so, I would suspect it is "normal" Winter loss of pigment, which, at least in my labs, got more pronounced as they got older.
If so, Spring will be here soon!!!!
