Which of the following is NOT a sign of conflict in a dog?

Playful barking is generally not considered a sign of conflict in dogs; rather, it is often associated with a dog being in a relaxed, social, or playful state. This kind of barking can indicate excitement and a desire to engage in play with other dogs or people. In contrast, the other options—panting with lips drawn back, a tail tucked between the legs, and darting eyes—are behaviors that typically suggest distress, anxiety, or conflict.

When a dog pants with its lips drawn back, it can be a sign of discomfort or a way to manage stress. A tail tucked between the legs is a classic sign of submission or fear. Darting eyes may indicate that a dog is feeling threatened or is uncertain about its surroundings. Understanding these signs is crucial in interpreting a dog's emotional state and responding appropriately. Recognizing playful barking as a healthy form of communication helps to differentiate between a dog's playful behavior and signs of potential conflict or discomfort.
