Dog Breeding

The responsible dog breeder must have a basic understanding of genetics.  This is how they can control things like color, size, and angulation.  


Let's start with genes.  A gene is the basis of heredity.  There are approximately 19,000 genes within an individual dog.  Genes are made up of DNA.  DNA is a molecule that is shaped like a spiral ladder; each rung of the ladder has two paired chemicals referred to as bases.
