The Blue Lacy Dog
The Blue Lacy Dog is the state dog of Texas, and the breed is the only one to have originated in the state.
According to Wikipedia, the Lacy dog was named after the Lacy brothers --- Frank, George, Ewin, and Harry Lacy, who in 1858 moved from Kentucky to Texas and settled in Burnet County. The dog, according to the Lacy family, was a mixture of English Shepard (or perhaps coyote), greyhound, and wolf. Texas House Concurrent Resolution No. 108 also mentions scenthound. The brothers originally developed the dogs' natural herding instincts to work the family's free-roaming hogs.
The Chapman and Lacy families are related. James Lacy, the father of John Bursey Lacy, was a brother of Harry Lacy of Kentucky. George Lacy, Barney Chapman’s uncle, was born to John Bursey Lacy in 1904 in Texas.
