........Why are some breeds sold as speciality dogs,whils others are just mixed breeds? Dogs such as Labordoodles are being sold as much as $500,Cockapoos and other dogs being sold as purebreds. My sister tried to explain this ,but it still makes no sense to me.I understand that some were bred down the generations,like a Bullmatiffs,which is 60 % bulldog and 40% mastiff. To me,a Labordoddle is a mixed breed,yet I have seen one in the paper for $500.Are they a accepable purebred? Just wondering and still confused.
