Customer: replied 8 years ago.
Reply to NancyH's Post: Mostly his back and head. some white around his eyes and 2 small stripes down his snout and a couple of patches on his back and many white hairs around his neck. and also, his nose and gums now have pink patches whereas they didn't 3 months or so ago. First his nose turned completely pink then it got most of the black back and now it's turning pink again.

That is a lot of color change. Many dogs do gray early in the muzzle area but with this much pigment change it might be due to a hormonal issue, a nutritional problem, or an autoimmune disease.
Vitiligo can cause loss of pigment. Dogs with vitiligo can develop patches of white hair or white hairs scattered in the hair coat.
Diseases such as lupus or pemphigus might also do this

A thyroid imbalance can lead to pigment changes too.
In male dogs that are not neutered an estrogen issue caused by a tumor on the testicles might be at fault.

If your vet is unable to help you track down the problem then you may want to ask them for a referral to a veterinary dermatologist.
