think long and hard about weather you want this type of dog.if you do then you have to decide what you want a gwp crossed with,greyhound,lurcher,saluki???????
like any cross they arent all the same,you have half crosses,dogs with just a quarter,or lurcher to lurcher bred.
some open up,my bitch didnt but she did round sheep up for a few weeks.
gwp cross,you would have to be mad
