What is a common reaction of dogs when feeling anxious in new environments?

When dogs find themselves in new and potentially stressful environments, a common reaction is to seek shelter or avoid stimuli. This behavior stems from their instinctual response to perceived threats, where they may feel the need to create a safe space for themselves. Seeking shelter allows them to regain a sense of security and reduce their anxiety by minimizing exposure to overwhelming sights, sounds, and situations.

In contrast to this, overly excited dogs may not necessarily be experiencing anxiety but rather excessive arousal or energy associated with excitement. Exhibiting calm and composed behavior is less typical when a dog is anxious, as anxiety often leads to restlessness or fidgety behavior. Running away from their owner could indicate extreme fear or anxiety, but it is not the most common initial reaction; often, dogs will seek a more secure location before resorting to bolting. Therefore, the choice of seeking shelter best encapsulates the typical canine response to anxiety in unfamiliar settings.
