HOST_Celluloid said someone put it there. He called him a "spy dog"
He should be an official NPC character that helps you out. Better yet, make him the first animal to be a staff member.
Have the dog wear a dog version of the staff uniform, put a collar that has the same color as the staff's ears, and his dog tag should be shaped like a Mickey or a dog bone. Nickname him "MyVMK_Pluto"
