Ain't that the truth but I don't think aggression is the right word. A good gwp can be one hell of a dog. My good mates line of dogs has produced some crackers, done well in the field from stalking to falconry and more. Great rough shooting dog and will whack a fox at the blink of an eye. These dogs are true HPR's, they will never beat a Lurcher at doing what lurchers do, but hell they are a very useful animal. Not to be underestimated in my opinion. The smooths are differnt to the wires, the wires tend to be a bit tougher.
