Why are some Siberian noses partially pink and partially black?

This is called a "snow nose", and is fairly common in the breed. A snow nose is a reddish or pink marking on a black or liver colored nose. Snow nose can disappear over warmer months and reappear over the winter months.

There is nothing wrong with a snow nose, and it is perfectly acceptable in the breed. See also the AKC Standard for the Siberian Husky (http://www.akc.org/breeds/recbreeds/sibhusk.cfm). More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
