only thing i know is ive never injured anything with a dog, its happened a few times with the gun and then i have to use a dog to find it given that the natural resources of the plannet we live on are dimminishing at a great rate of knotts doesnt it seem daft to be doing things this way still, when just by using a dog fit for the purpose we wouldnt need the gun,ammo,bipod,cammo gear and every other accesory on the market. thus reducing our carbon footprint, and thus saving our plannet. so as i said progress isnt always for the better
