I am the owner and handler of ammo Vom cooper when I got ammo he was just about a year and a half old they they tried to do some training with him hoping to train him for police work turned out ammo was too aggressive for that so the person who owned ammo is good friends he was giving up on him then I took ammo worked with him and he turned out to be awesome dog It took time and patience with him I myself did all the training with him besides bringing in a decoy to do Bite work but he turned out really good ended up doing private security work with me as the handler this dog has literally saved my life he did his job and did it well he has since retired
