Labradors are relatively large, with males typically weighing 30–36 kg (65–80 lb) and females 25–32 kg (55–70 lb). Labs weighing close to or over 100 lbs are considered or having a major fault under standards, although some labs weigh significantly more. Their coats are short and smooth, and they possess a straight, powerful tail often likened to that of an The majority of the characteristics of this breed, with the exception of colour, are the result of breeding to produce a As with some other breeds, the English (typically "show" or "bench") and the American (typically "working" or "field") lines differ. Today, "English" and "American" lines exist in both the United Kingdom and in North America. In general, however, in the United Kingdom, Labs tend to be bred as medium-sized dogs, shorter and stockier with fuller faces and a slightly calmer nature than their American counterparts, which are regionally often bred as taller, lighter-built dogs. 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. Other "local minor variants" may also exist in some areas.
The breed tends to hair twice annually, or regularly throughout the year in Some labs shed a lot; however, individual labs varyLabrador hair is usually fairly short and straight, and the tail quite broad and strong. The -like tail and of the Labrador Retriever make them excellent swimmers. Their interwoven coat is also relatively waterproof, providing more assistance for swimming. The tail acts as a rudder for changing direction.

Colour
There are three recognised colours for Labs black (a solid black colour), yellow (anything from light cream to gold to "fox-red"), and chocolate (medium to dark brown). There are no such things as silver or golden Labradors, a common mistake for the Yellow variant. There is also a black-and-tan coat type, but this coat colour is the least popular as it renders the Labrador un-showable except in the UK.
Puppies of all colours can potentially occur in the same . Colour is determined primarily by two genes. The first gene (the B locus) determines the density of the coat's pigment granules: dense granules result in a black coat, sparse ones give a chocolate coat. The second (E) locus determines whether the pigment is produced at all. A dog with the recessive e allele will produce little pigment and will be yellow regardless of its genotype at the B locus. Variations in numerous other genes control the subtler details of the coat's colouration, which in yellow Labs varies from white to light gold to a fox red. Chocolate and black Labs' noses will match the coat colour.
