Here is part of a web site by the  
Department of Animal and Poultry Science 

University of Saskatchewan 

Saskatoon, Canada S7N 5A8 



Some pure white animals are albinos. Little discussed albinism in dogs but this condition is probably rare. This white Samoyed/Husky cross has a black nose and eyes and is therefore not an albino. Little suggests that the white of Samoyeds is due to the allele (sw), which he claims is the lowest allele of the series at spotting, meaning it is the most recessive in that series. However, this crossbred suggests that Samoyed white is dominant. No data are yet available for which gene actually causes this white or the white of Great Pyrenees.

This site is purported to be a summery of the accepted publications on the Color in Dogs and used Little's work as its main template.

The subject is not definitive at all and we should look carefully at it.
