How can a dog signal submission when interacting with others?

A dog signals submission primarily by lowering its body and presenting its belly. This behavior is a clear sign of yielding or deference to another dog or person, indicating that it poses no threat and is acknowledging the other’s higher status in the social hierarchy. When a dog displays its belly, it is demonstrating trust and vulnerability, as this area is sensitive and less protected. Such a submissive posture can foster a peaceful interaction and is often a way for dogs to avoid conflict.

In contrast, raising its head high, wagging its tail fiercely, or standing tall and assertive are behaviors typically associated with confidence, dominance, or excitement rather than submission. These actions do not communicate an intention to appease or show deference, which further highlights why option B is the best representation of submission in canine interactions.
