If i am correct a lurcher is a sighthound i.e greyhound crossed with anyother breed to create a lurcher they can be long hair,short,broken coated.
The breeding for example the percentages of cross is important to create the dog you require for your sport for example a small fast dog for rabbiting i.e bedlington/whippet or for bigger game greyhound/saluki cross.
This is my best pal in the world
