Your 'mean' dog is shut away unable to help. My well socialized, obedience trained dog is sitting calmly next to me the whole time. The second way is you will be literally giving this dog a death sentence if he should ever get out from open gate because of hurricane, tornado or negligence. Hope to hear from you soon. Gidget Animals kill to protect their young or territory and to eat.
Man kills for no other reason than pleasure, it's fun.
