Here's a breakdown of what this behavior means:
* Greeting: It's a way of saying hello and acknowledging the other wolf's presence.
* Submission: The wolf putting its head under the chin is demonstrating its lower social status. This is a way of showing respect to the dominant wolf.
Other behaviors that accompany this gesture include:
* Tail wagging: The tail might wag slowly or be held low.
* Licking the face: This is another way of showing deference.
* Vocalizations: Wolves might make soft whimpering or grunting noises.
Important Note: This behavior isn't always strictly about dominance. Wolves may also use this gesture to show affection or to reinforce bonds within a pack.
