Question: The Blue Lacy, official breed of Texas, and Chesapeake Bay Retriever, are both dog breeds developed during which century?

<P0-S0> Twelve states of the United States have designated an official state dog breed. <P0-S1>  Maryland was the first state to name a dog breed as a state symbol, naming the Chesapeake Bay Retriever in 1964. <P0-S2>  Pennsylvania followed the year after, naming the Great Dane as its official breed. <P0-S3>  Dog breeds are mostly affiliated with the states that they originated in. <P0-S4>  North Carolina chose the Plott Hound as it was the only dog breed indigenous to the state. <SEP> <P1-S0> The Lacy Dog or Blue Lacy Dog is a breed of working dog that originated in Texas in the mid-19th century. <P1-S1>  The Lacy was first recognized in 2001 by the Texas Senate. <P1-S2>  In Senate Resolution No. 436, the 77th Legislature honored the Lacy as "a true Texas breed". <P1-S3>  In June 2005, Governor Rick Perry signed the legislation adopting the Blue Lacy as "the official State Dog Breed of Texas". <P1-S4>  As expected, the vast majority of Lacy dogs are found in Texas. <P1-S5>  However, as the breed becomes more well recognized, there are breeding populations being established across the United States, Canada, and most recently in Europe. <SEP> <P2-S0> The American Russell Terrier Club (formerly named the English Jack Russell Terrier Club), founded by JoAnn Stoll in 1995, was the first registry in the United States to maintain the Russell Terrier as a separate breed from the Parson Russell Terrier. <P2-S1>  The American Jack Russell Terrier Club is affiliated with both the United Kennel Club and the American Kennel Club. <P2-S2>  The purpose of the early founders was to establish a registry for the perpetuation and development of the Russell Terrier as a pure strain of working Jack Russell Terrier keeping their blood and type pure within the registry to works towards Kennel Club recognition as an official breed in the US. <P2-S3>  On January 1, 2001, the United Kennel Club recognized the Russell Terrier as an official breed, designating only the stock from the American Russell Terrier Club as Foundation stock for the UKC Russell Terrier. <P2-S4>  In 2004 the American Russell Terrier Club submitted an official request to include the American Russell Terrier Club stock into the AKC FSS Program to work towards becoming an official breed under the perimeters. <P2-S5>  On December 8, 2004, the AKC officially accepted the Russell Terrier. <SEP> <P3-S0> The Chesapeake Bay Retriever is a large-sized breed of dog belonging to the Retriever, Gundog, and Sporting breed groups. <P3-S1>  Members of the breed may also be referred to as a Chessie, CBR, or Chesapeake. <P3-S2>  The breed was developed in the United States Chesapeake Bay area during the 19th century. <P3-S3>  Historically used by area market hunters to retrieve waterfowl, it is primarily a family pet and hunting companion. <P3-S4>  They are often known for their love of water and their ability to hunt. <P3-S5>  It is a medium to large sized dog similar in appearance to the Labrador Retriever. <P3-S6>  The Chesapeake have a wavy coat, rather than the Labrador's smooth coat. <P3-S7>  They are described as having a bright and happy disposition, courage, willingness to work, alertness, intelligence, and love of water as some of their characteristics.
