Uggie, the canine star of “The Artist,” attended the 84th Academy Awards wearing nothing but a dashing black bow tie and a sweet expression.

Alarm bells were raised in mid-February when a spokesperson for the Weinstein Co. told Reuters that Uggie had “not been asked to participate or appear at the Oscars.” This seemed to be confirmed when the dog did not appear on the Oscars red carpet Sunday. But all fears melted away, as Uggie’s mug flashed across the screen during a sketch with host Bill Crystal.

Uggie also got a mention during Michel Hazanavicius’s acceptance speech for best director.

“I want to thank Uggie, the dog. I think he doesn’t care. I’m not sure he understands what I say,” Hazanavicius said, before throwing a bone to the Uggie haters out there: “He’s not that good, but thank you.”

(Hazanavicius isn’t the only one who showed some contempt for Uggie in recent months. Oscar winner Christopher Plummer, director Martin Scorsese and a few others actors have dissed the dog.)

Uggie also appeared onstage as the film’s producer, Thomas Langmann, Hazanavicius and “The Artist” cast accepted the Oscar for best picture.

By all accounts, this will be Uggie’s final awards show appearance. The 10-year-old Golden Collar winner is suffering from a “mystery shaking syndrome” and will now retire from the film industry, according to his trainer.

As we look back on this awards season, it’s safe to say that it wouldn’t have been the same without the four-legged guy who put on a show at the Golden Globes and stole our hearts. See more photos of Uggie at the Oscars below.
