Summary
This quote implies that the behavior and social tendencies of a puppy differ greatly from those of an old dog. A puppy is playful and eager to engage with others, welcoming any interaction with fellow pups. On the other hand, an old dog is more selective and has limited companionship. Metaphorically, this quote suggests that youth is often characterized by openness and a willingness to form connections, while age brings more discernment and a smaller inner circle of relationships.
