LISMORE fox terrier Lex Luthor truly is Australia's top dog.
According to his owner, Lee Rushforth, since her four-year-old foxy took out Best in Show at the Purina ProPlan Sydney Royal Dog Show on Monday, he has been "full of his own self-importance".
The foxy was nonplussed by the Sydney Royal ribbon but tail-waggingly chuffed with a pavilion of applause, a lick of champagne and his favourite reward - chicken McNuggets.

"He knows he's top dog. The more people clap and cheer, the happier he gets. He is very noise-activated," she said.
After winning Best in Breed, Lex was one of just seven dogs in contention for Australia's most prestigious dog title, selected from more than 4000 pooches which took part over the 14-day event.
Lex comes from a long line of winners - his father won Best in Show previously and his mother won Best in Show in Brisbane.
"Lex hadn't been shown in about six months so to win Best in Breed was wonderful but this is unbelievable. There were so many beautiful dogs competing this year which makes the win all the more special. Everyone wants to win Sydney Royal so we are over the moon with the result - I really couldn't be more proud of him," she said.
Ms Rushforth confirmed the stereotype, cast by the 2000 mockumentary Best in Show, of the competitive show dog circuit as filled with cut-throat Type A personalities.
"There are some big personalities at these shows. Everybody thinks that they take home the winning dog on the day. In my case, this time, I really did," she said
Ms Rushforth said Lismore punched above its weight in the dog show ring.
"We have a lot of really dedicated dog breeders, owners and handlers here," she said.
The dog lover added Lismore would benefit from more fenced dog parks but the biggest local problem was untrained puppies.
"It's so important to socialise your dog. Get your dog to puppy preschool," she said.
Ms Rushforth admitted her show stealer pooch lived up to his villainous name.
"He's a true terrier. The clown of the dog world," she said.
