Sirius is Thomas Trelone's great experiment - a huge, handsome dog with the brai
n and intelligence of a human being. Raised and educated in Trelone's own family
alongside Plaxy, his youngest daughter, Sirius is a truly remarkable and gifted
creature. His relationship with the Trelones, particularly with Plaxy, is deep
and close, and his inquiring mind ranges across the spectrum of human knowledge
and experience.
