An Amerindian is the way you call your dog if you really think he is wild. To test that information, you may start trowing rocks at him. If it barks, it is fucking wild. Then you may buy an ice cream from Dairy Queen and eat it, in front of your fucking wild dog, smiling and kind of mocking, and then shove it for fun. Then, in the nearest future, you may call him an "Amerindian" and dress it up with many feathers or pieces of decorticated fur coats.
