They carry their tails high and stand tall. The less dominant wolves keep their tails low and often lower their bodies while pawing at the higher ranking wolves. If two wolves have a disagreement, they may show their teeth and growl at each other. Both wolves try to look as fierce as they can. To show that it gives up, the wolf rolls over on its back and the other wolf stands over it.
Wolves communicate other things with their bodies, too.
If they are angry, they may stick their ears straight up and bare their teeth. A wolf who is suspicious will pull its ears back and squint. Fear is often shown by flaftening the ears against the head. Wolves mark their territory with urine and scat. This is called scent marking.
