 As with some other breeds , the Conformation ( typically " Show " , " English " or " bench " ) and the Field ( typically " Working " or " American " ) lines differ , although both lines are bred in both countries . In general , however , Conformation Labradors tend to be bred as medium @-@ sized dogs , shorter and stockier with fuller faces and a slightly calmer nature than their Field counterparts , which are often bred as taller , lighter @-@ framed dogs , with slightly less broad faces and a slightly longer nose . However , Field Labradors should still be proportional and fit within American Kennel Club standards . With Field Labradors , excessively long noses , thin heads , long legs , and lanky frames are not considered standard . These two types are informal and not codified or standardised ; no distinction is made by the AKC or other kennel clubs , but the two types come from different breeding lines . Australian stock also exists ; though not seen in the West , they are common in Asia . These dogs are also very good with children .
