My sibe is known as a blk/white on his pedigree but as he is growing now 4,1/2 months he looks more like a agouti according to the husky colours site. Searching for info. from the site it does not look to me like agouti colour huskies do well in show. Am i right in thinking this? It is ok to me because i wasnt going to show him anyway but just to take him to companion shows would make me happy he has quite full markings on his face so did his mum but dad had a more white face like what i call a traditional husky look.  Does the agouti come more from racing lines as his mum was show and dad was racing.  My sibe is also 20,1/2 inches to the shoulder at this age is he likely to be a oversized husky or just right is it 23 or 23,1/2 wasnt sure.   thankyou for any info. on this subject.

Can you not talk to his breeder?

colour is irrelevant in sibes, if the dog has the correct construction and movement, he could do ok in the ring.  obviously some judges have colour preference but colour should not influence their judging.
colour and markings change so much in sibes anyway, he may change again!
