I would love to address this concern, even though it was posted so long ago.
I am a veterinary technician and on my second pit (this one whiter than the first). Both have sensitive skin.
The best thing I have every done that has yielded the best results is
clean living. Eliminate toxins where ever possible. And they are everywhere, so look everywhere. Filter the water, don't use fragrances of any kind (candles, plug ins, perfumes, fabric softeners, cleaning products...), clean food including any people food (i.e. organic strawberries, not frosted mini wheats), and so on and so on. Anything that you can think of, purify it as much as possible. The less contaminates and toxins they have to deal with, the easier it is for them to maintain health. The same principle applies to allergens. reduce the allergens, and they can cope much better.
This may seem extreme until you realize how much it helps you and everyone else in your family. When the illnesses lessen, everyone is so much happier and can really enjoy life.
One other big thing I did was give up on all the medicated shampoos. Not only are the very costly, they don't work for more than a few hours! I now bathe my pets only with Shaklee's Basic H. (If you need a link to get some, just pm me.) That has INSTANTLY relieved every single skin irritation they have ever had and has given them the softest and healthiest skin and coats I've ever seen! The company's sunscreen is also safe enough to use around even fish tanks. So I dab it on my girl's nose and ears before going on our hikes.

Hope that helps you and anyone else reviewing this. I've been so very happy with our results!

I got him at two months back in July, but he didn't go out much, except for the bathroom, he pretty much just slept all the time for the first two months after I had him. I live in SC so the sun isn't as bad here as say, FL or something. But this will be a concern this summer, esp b/c I take him everywhere I can with me. So do they make like a doggie sunblock or something, or do I just use human? And what if so what kind? (spf, for kids, spray, lotion, etc.)
