Puppy love is a term often used to refer to a young romance or infatuation. Some synonyms for puppy love include a crush, infatuation, fling, dalliance, or a teenage romance. While puppy love may be looked down upon as immature, it is a natural part of growing up and developing romantic feelings. It can be fleeting, much like a crush or infatuation, but it can also lead to long-term relationships or even marriage. Regardless of how it turns out, puppy love is a significant milestone in a person's emotional and social development.
