one of my bitches has a pigment problem on her nose at the moment....it
was pink .
I gave her elderberry and nettle during the summer months but after September Dorwest reccommend that you use Kelp Seaweed (available on thier website)
Be prepare to wait months for it to return they say it most likely will if it was there in the beginning and luckily for us we are nearly back to normal.......but it has been 4m
Also if you have a bitch it can be related to her season.
