The lurcher is a type of dog, rather than a breed. Lurchers are typically a crossbetween a sighthound and another breed. Collie crosses are popular usually as it brings the benefit of intelligence and working instinct of the sheepdog to the strength and speed of the sighthound, creating a fast and adept hunting dog. Some terrier breeds are also popular crosses, and offer great tenacity and hunting instincts.

Most terrier breeds have evolved in Great Britain and Ireland. Traditionally these hard working dogs were used to control vermin such as rats, rabbits, and foxes. Some larger terriers were also used to hunt badgers, although this practice is now outlawed.

Terriers are adept at hunting both above, and below the ground. In fact, the word terrier comes from the French word ‘terrier’, which itself is derived from the Latin word ‘terra’ meaning earth. There are notable exceptions including the Kerry Blue Terrier and Airedale, which were particularly noted for tackling river rats and otters in deep water.
