My dad and his friends plan to eat my dog! :(.?

My dad is an alcoholic dude, he have this friends who already ate dogs :(.. I have this one dog who's kinda skinny but still very energetic and he's mixed dog too.. My dog(we have many dogs) is in our yard and we have someone to take care of him but that someone also eats dogs! He's just so playful so everytime my dad's friends come by( which is crazy alcoholics) he will jump over them but not hurt them.. They're also annoyed by this and because of my dad's friends stories about eating dogs.. He and his friends plan to eat my dog.. My aunt also disposed 2 of my dogs when I was not around before because they're too old and have many fleas so they put them in a farm with no owner where many dog eaters can get them or just die there and said to me they just ran away.. What should I do??? I need to go to school but what if I come back not seeing the dog they plan to kill.
