It was Annie, a service dog who was noticed on Twitter after she was seen in the background of a picture of Nashville defenseman Roman Josi, that was all the talk on social media.

P.K. Subban scored a goal in his regular-season debut with the Nashville Predators on Friday but he may have been upstaged at Bridgestone Arena.

Annie, a yellow Labrador retriever, is a service dog for Predators fan Josh Ray who was at the game sitting in the front row. The photo was taken by Associated Press reporter Jim Diamond and social media was abuzz wondering about the dog seen in the background of the picture. Coincidentally, the dog is above an advertisement for Pedigree dog food.

Annie graduated from Retrieving Freedom, which trains service dogs for wounded veterans and children with autism, a few weeks ago before being placed with Ray.

According to Diamond, Ray said it was Annie's first hockey game but she remained perfectly calm during the tension-filled game, particularly in the third period.

The Predators defeated the Chicago Blackhawks 3-2.
