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.
One thing that is especially important to keep in mind is that this breed has a tendency to retain weight if it is sedentary too often, or if it is given too many treats. One of the most common health problems for the modern Labrador dog is obesity. A healthy Labrador should have a trim, hourglass shape. While it may be tempting to treat your Lab pal often, in return for their unconditional affection, it is far better to treat your friend with quality playtime rather than edible treats. This will ensure that you and your Lab will enjoy a long and healthy companionship. Labradors do very well outside with a doghouse, as they are adaptable for outdoor conditions, but they prefer to live indoors, close to people, most of the time.
We love that it’s made in the U.S. (in Santiago’s home state of Texas), using FDA food-grade and eco-friendly materials. While it comes with a hefty price tag, it pays for itself in no time in the cost a pup parent pays for daycare or replacing destroyed items in the home from a bored dog. Best of all, you don’t have to worry about them breaking the outside because it’s completely replaceable.
