Instinct...

Tinternet tells you that the crossbreeding of the labrador retriever and German wire haired pointer can - if you're lucky - result in a remarkably fine HPR (hunt, point, retrieve) animal.

Now, I know that's as far away from the reason I've got her as it's possible to be, and I know she's only six months old, but there's a tiny roe deer minding its own business just down at the treeline here, and I wasn't necessarily expecting the pup's response to be "run away!!!"
