The Jack Russell terrier was a small, energetic breed of dog, so named because it was originally bred by John "Jack" Russell for the purposes of fox hunting.[1] It was primarily white with the occasional black or tan marks.[1]

Ronald Weasley's Patronus took the form of a Jack Russell terrier.[2] He first used it during a Dumbledore's Army meeting in the 1995–1996 school year.[3]

The Crup, a magical creature similar to a dog, was described as looking like a Jack Russell terrier with a forked tail.[4]

Behind the scenes

  • J. K. Rowling chose the Jack Russell terrier as a sentimental choice for Ron's patronus, because she had a Jack Russell terrier, whom she stated to be "insane."[2]
