Here I am again banging on about the same subject, but I am totally perplexed about my white Shepherd's nose! It was a lovely black when he was a pup, as were his lips and paw pads, but now they are all pink, with his nose being the worst, its horrible!
I have tried kelp, elderberry, not feeding from plastic bowls, nothing is working. Funnily enough, he still has fairly dark rimmed eyes, so he's not completlet lost his pigment, but I am at a loss to understand why his nose is like this now when it was so dark as a pup. Its not just a snow nose either as he has had this for about a year. Has anyone else got this problem with their dogs?

My girls go like that when they have been poking about in mole hills. Sometimes it get worse during the winter. Some people say only give boiled water or bottled water. Could be something in your water that does it.

I had a litter of pups in the autumn and one new owner asked about pink noses because her previous dog had had one and she didn't want it again. All mine usually have good pigment and the pup she had did. Within a week of her having the pup the nose started to go paler. That is the only pup out of 8 with a pale nose. That must say something and asked around and the majority vote was change the drinking water. Other than that sorry can't think of anything else tried all the same things as you over the years, never really came up with a cure.
