A lurcher is a crossbred dog resulting from mating a greyhound or other sighthound with a dog of another type such as a herding dog, terrier or working dog. The lurcher is not a “breed”: the term is a generic descriptor of a diverse group of dogs. They are known for being loyal, fast, and versatile. For hundreds of years, lurchers were strongly associated with poaching; in modern times, they are kept as hunting or companion dogs.
