#10 Various preceding dog species were involved in the creation of the Rat Terrier.
While smooth-haired fox terriers and Manchester terriers were first crossed at the beginning of the 19th century, the beagle and whippet were later added, which together led to the emergence of the Rat Terrier breed.
#11 It was named after Teddy Roosevelt, who had a special fondness for dogs.
The name points to the original breeding goal of the dogs as pied pipers on American farms. This use made them one of the most popular farm dogs in the United States in the early 1900s.
#12 Due to the increased use of chemical raticides, however, fewer and fewer dogs have been used in this context since 1940, so that their population has also declined.
The dog breed is not recognized by the FCI but is represented by the AKC.
