Yes, i know that the chestburtsters develops inside its host and take over iets charactistics, but the 'normal alien' doesn't look very human too me. And the 'Dog alien' came from a dog but dogs have haires. And the dog alien doesn't have haires, and big ears. the dog alien looks very same like the alien came from a human. So why does the predalien suddenly looks like a pred with haires and stuf and the jaws?
