 While individual dogs may vary , in general show @-@ bred Labradors are heavier built , slightly shorter @-@ bodied , and have a thicker coat and tail . Field Labradors are generally longer legged , lighter , and more lithe in build , making them agile . In the head , show Labradors tend to have broader heads , better defined stops , and more powerful necks , while field Labradors have lighter and slightly narrower heads with longer muzzles . Field @-@ bred Labradors are commonly higher energy and more high @-@ strung compared to the Labrador bred for conformation showing while conformation breeds are calmer in energy , and as a consequence may be more suited to working relationships than being a " family pet " . Some breeders , especially those specialising in the field type , feel that breed shows do not adequately recognise their type of dog , leading to occasional debate regarding officially splitting the breed into subtypes .
