The Rat Terrier is an American crossbreed that originated in the 19th century. These terriers were bred primarily as farming and ranching dogs that were able to help eradicate vermin, protect livestock, and chase small game animals. President Theodore Roosevelt, who named these dogs, owned several Rat Terriers himself. Inquisitive, smart, and affectionate, these dogs exude spunk and enthusiasm for play and for their loving guardians. Fans of the terrific Rat Terrier will love this wall calendar.
