What animal is Ron's Patronus?

The story behind the answer

Ron Weasley’s Patronus is a Jack Russell Terrier. He first conjures it during Dumbledore’s Army practice, and it appears again to repel Dementors. The terrier’s form signals Ron’s brave, loyal, and protective nature—small but fearless, much like his role among friends.

Patronuses reflect personality and attachments. J.K. Rowling noted she chose a Jack Russell for Ron because the breed is known for chasing otters—a playful nod to his feelings for Hermione, whose Patronus is an otter. Memory tip: Ron runs after Hermione, just as a terrier chases an otter. Remember that a Patronus is powered by a happy memory, making its animal shape a personal emblem of the caster.
