What does gentle biting of hands by dogs mean?

Gentle biting of hands by dogs, often referred to as "mouthing," is typically a form of play and communication. Puppies, in particular, use their mouths to explore their environment and interact with others. This behavior can also indicate excitement or affection, but it's essential to monitor and redirect it to prevent any accidental injury. Encouraging appropriate toys for chewing and providing positive reinforcement for gentle interactions can help manage this behavior.
