Hi from the U.S.A.--I have one cairn (so far), a joyful 4 yr. old S.F. My readings have left me unclear on one point--in the UK is non-solid white (white with dark mask &/or points) acceptable?

Goodmorning Guest,
I know nothing of the finner points of the Cairn, don't even know what S.F. is. Have looked at the standard and it would appear that if he is solid white with a black mask, he is very boarder line, and I don't think I have ever seen a white cairn at a show, black mask or not, it would not stop you showing him as in the UK we do not have disquilifing faults, but he may not have too much luck. The only way to find out is to take him to a show and see how he is received.
If you can't have success showing him never mind just love him. JH
