Just say hese 25/25/50, its as near as dammit anyway mate and it dont matter really so long as he does what you want of him. Mine that i picked up on saturday is border, beardie, grey and i dont even know the percentages, i never remembered to ask! I know hese more grey than collie, i can see the "long dog" in his deep chest and general shape even at just 6 weeks old. Its easy to get to anal about the maths sometimes, just enjoy him mate. Kev.
