Lurcher or longdog?
A Lurcher is not a specific dog breed; it is a type of dog.
Lurchers were originally bred by intentionally crossing a sighthound with a herding breed. Historically, greyhounds and herding breeds such as Border collies were used simply because they were the most readily available to breed from.
However, the origins of the modern lurcher can vary greatly according to the breeds used for crosses, so Border Collies, German Shepherds, Australian Sheepdogs, Bull Terriers, or Bedlington Terriers can be used. Among the sighthound breeds, Greyhounds, Salukis, Deerhounds, Ibizan Hounds, Pharaoh Hounds or even Borzois can be used.
It is helpful to clarify the difference between a ‘lurcher’ and a ‘longdog’.
