Quick answer

A loose, relaxed lean is often a social contact behavior. A tense or urgent lean in a difficult setting may be a request for support rather than a simple display of affection.

Contact can be rewarding

Physical proximity is part of many dog–human relationships. Leaning can maintain contact without requiring active petting.

Support-seeking looks different

In a noisy or unfamiliar place, leaning may come with scanning, panting, tucked posture, or reluctance to move. Helping the dog gain distance can be more useful than insisting they stay.

Choice keeps contact comfortable

Avoid pinning a leaning dog in place. Let them reposition, and use pauses during touch to check whether they choose to continue.
