The Jack Russell terrier is a breed of dog, so named because it was originally bred by Parson John "Jack" Russell for the purposes of fox hunting. It is primarily white, with the occasional black or tan marks.
The Jack Russell is a broad species type, with a size range of 10–15 inches or 25–38 cm. It is an energetic and often ocnsidered "dizzy" breed of dog that relies on a high level of exercise, regular activities and stimulation and it is also relatively free from serious health complaints due to it's lack of specially bred features.
