What would happen if you bathed a mostly white dog with non-white markings with a whitening shampoo? Would something happen to the non-white markings? The thing is, Basil is about 80% white, with brown markings on his face/ears and lower back/tail area. Some of his white fur, like on his paws and tail, tends to get a little yellow, so I was considering trying a whitening shampoo on him. However, I don't want to mess up his gorgeous brown markings, so should I use two different shampoos, one for his white fur, and one for his brown fur? Or will he be okay with just whitening shampoo?

It won't harm the color bits. It'll just 'brighten' the white bits.

Keep in mind that you may have to use the whitening shampoo regularly for a bit before it will brighten the white to it's full capacity.

I have always used a white brightening shampoo on Lola. Had her for well over a year and as you can see it has had no affect on the other colors.
