My dog Oskar ir a pure lab, he chases things all the time but then has no idea what to do when he catches whatever it is he is chasing.
I personally feel a lot better that my dog is not a killer. I have a two year old daughter.
He'll chase a cat, corner it then stand there staring at it hoping it wont scratch his eye balls out... lol.
He caught a baby magpie in his mouth once, decided he would show off and bring it to me, but I kind of insisted he drop the thing seeing as it's not to happy parents where swooping us...
