Dog coat color is governed by how genes are passed from dogs to their puppies and how those genes are expressed in each dog. Dogs have about 19,000 genes in their genome [2] but only a handful affect the physical variations in their coats. Most genes come in pairs, one being from the dog's mother and one being from its father.

Puppies are markedly underdeveloped and dependent on their mothers at birth (displaying altriciality), but healthy puppies grow quickly and begin walking thereafter. Puppies generally weigh 8–16 oz (0.23 ...
When a dog has wild-type alleles at all three genes, it will have a yellow coat. When the dog has a loss-of-function allele at MC1R, it will have a yellow coat regardless of the genes it carries on the other two genes. Only a dominant black allele at CBD103 will produce a black coat color in dogs possessing wild-type alleles at MC1R and Agouti. [8]
If your puppy is biting you, don't redirect them with a toy, though. When you give them a toy to bite on in exchange for your hand, you're rewarding the biting behavior.
Dog breeding became more systematic to preserve unique mutations such as shortened legs, a shortened face, new fur colors and textures. [6] The increased popularity of dog shows that judged a dog's look more than its working ability led to different goals when breeding. [ 11 ]

In comparison, a group of eggs and the offspring that hatch from them are frequently called a clutch, while young birds are often called a brood. Animals from the same litter are referred to as littermates.
