You pad outside, slippers on, for the dog’s morning constitutional. Coffee in one hand, your phone in the other, your leash awkwardly wrapped around two fingers. The dog yanks a little too hard, and you fling your coffee all over yourself. Forget all that. Use a hands-free leash like this one. It wraps around your waist so you can run, bike, or just amble around the front yard with both hands still free.
Puppies of all colours can potentially occur in the same litter. Colour is determined primarily by three genes. The first gene (the B locus) determines the density of the coat's eumelanin pigment granules, if that pigment is allowed: dense granules result in a black coat, sparse ones give a chocolate coat. The second (E) locus determines whether the eumelanin is produced at all. A dog with the recessive e allele will produce only phaeomelanin pigment and will be yellow regardless of its genotype at the B locus. The genes known about previously have had their number increased by the introduction of the K locus, where the dominant "black" allele KB is now known to reside. Black or chocolate Labradors therefore must have the KB allele. Yellow Labradors are determined at the E locus, so the K locus is irrelevant in determining their colour. Variations in numerous other genes control the subtler details of the coat's colouration, which in yellow Labradors varies from white to light gold to a fox red. Chocolate and black Labradors' noses will match the coat colour.
Labrador Retrievers love, love, love to eat, and become obese very quickly if overfed. Limit treats, give your Lab plenty of exercise, and measure out regular meals rather than leaving food out all the time. And be warned that the Lab's large appetite extends to people food and even inedible items. Labradors will forage in garbage, counter surf, and can make a meal out of chewed-up items like children's toys.
In the United States, the breed gained wider recognition following a 1928 American Kennel Gazette article, "Meet the Labrador Retriever". Before this time, the AKC had only registered 23 Labradors in the country, in part because US and UK hunting styles had different requirements. Labradors acquired popularity as hunting dogs during the 1920s and especially after World War II, as they gained recognition as combining some of the best traits of the two favourite United States breeds as both game finders and water dogs.
