The Labrador Patronus

• Type: Patronus form
• Owners: Unknown in the primary canon. A possible form for a witch or wizard (Pottermore).
• Maker: N/A (Produced by the Patronus Charm)

A corporeal Patronus in the shape of a Labrador, a breed of retriever dog. It manifests as a silvery-white, translucent entity, radiating the positive feelings of hope and happiness required to cast the charm. The physical characteristics would mirror those of a real Labrador, known for its sturdy build and friendly, gentle demeanor.

As a Patronus, a Labrador form acts as a powerful guardian. Its primary magical property is its ability to repel Dementors and Lethifolds, which prey on human happiness and life force. The Patronus functions as a shield of concentrated positive energy that these dark creatures cannot feed on or penetrate. A Patronus of this form can also be used for communication. The caster can send it to another witch or wizard to deliver a message, which is spoken in the caster's own voice upon arrival.

There are no recorded instances of a character casting a Labrador Patronus within the seven original Harry Potter novels. The form is not associated with any specific character in the primary canon.

The Labrador Patronus does not play a direct role in the narrative of the Harry Potter series. Its significance in the wizarding world is derived from its existence as one of the many possible forms a corporeal Patronus can take. The form is thought to reflect the caster's personality; a Labrador might suggest traits such as loyalty, friendliness, reliability, and a protective nature.

• The Labrador is one of the many possible Patronus forms a user can be assigned after completing the official Patronus quiz on the Pottermore (now Wizarding World) website (Pottermore).
