Giving someone else the leash (literally and figuratively).

In modern romance, a dog often serves as a "character litmus test." Authors use a character’s relationship with a dog to signal their capacity for empathy, patience, and commitment to the reader.

In many romantic comedies, the dog is the primary engine of the plot. Think of the classic trope: two strangers are pulled together when their leashes get tangled in a park, or a runaway golden retriever leads its owner straight into the arms of a soulmate.

If a cold, career-focused protagonist softens the moment they see a scruffy terrier, the audience knows there is a heart of gold buried underneath the suit. Conversely, if a potential love interest is unkind to a canine companion, it serves as a massive red flag, signaling to the protagonist (and the audience) that this person isn't "the one."
