Hi,
White Golden Retrievers are unacceptable and deemed as a fault,therefore most good,careful sensible breeders breed within the acceptable colour range as required by the breed standard.As Snomaes correctly said a well bred pup may appaear white very little if bred correctly, will ALWAYS be pale cream when older.
The Standard clearly says a pure white coat like that of A Samoyed is incorrect.
Also the red/mahogoney colour of the irish red setter is also incorrect.
The range of colour is from cream to dark gold.
Just out of interest the American standard calls for rich,lustrouus various shades of golden.Feathering maybe lighter than rest of coat.
Predominant body colour extremely pale or dark is undesireable.
There are many excellent breeders of both beautiful pale cream dogs in our country as well as more golden shades.
Hope you find what your looking for

and hope for the good of the breed its not a "white" pup just my opinion.
