How far would you go to protect your pet from those wanting to feed off of it?

If you others felt eating your pet was the way to survive how far would you go to stop them? Say, you (and one other person close to you) were traveling to a remote and rugged location for an extended assignment for work or getaway where you can only fly in or hike nearly 5 days with pack animals during winter and plane goes down. Being it is a small plane, large enough for the pilot, co-pilot, 5 other people (6 others if 2 are children) and you. Most of all the supplies are already there waiting but you have an estimated 3 days worth of food with you. The crash kills the co-pilot, and the pilot and one of the others are bad off and in a coma, your person and another passenger is banged up to the point they cannot be moved with out extreme pain to them. The radio is busted, there are no cell towers, and no one has a satellite phone; you all are cut off from the outside world. Your pet survived because it was in a cage and at the rear. It will be at least two days before you are discovered missing and anyone starts to search, because of the harsh weather times an aerial search can happen is slim. No matter what you try you can’t bring attention to yourself. Because of the dead co-pilot and the 2 comatose people you stretch 3 days food into 9 (they make you feed your pets from your rations), but then it runs out. Rain or snow get you water so you can hold out, but at some point if the rescue drags out to many weeks and the others start feeling the pangs of hunger. One of them suggests killing your pet because no one has eaten really in two weeks. How far would you go to let them know (pet name here) is not on the menu? Would you be willing to kill one (or more) of them should they tried to harm your pet? If one or more offered you a large bribe and had the cash on them would you think about it? If one of the others had a child and begged you to do it, so they can feed their kid would that change your mind any?
