Dogs are mammals that have been domesticated from wolves since 15,000 years ago, [3] perhaps even 100,000 years ago based on genetic evidence in the form of fossil discoveries and DNA testing. Other studies reveal the history of domestication of dogs that have not been so long.

Dogs have developed into hundreds of breeds with various variations. Dog hair colors can vary, from white to black, also red, gray (often called "blue"), and brown. In addition, dogs have various types of hair. Dog hair can be straight or curly, and has rough to soft texture like wool yarn.
