Who is the animal statue of in the Game of Thrones Season 8 Teaser Trailer?

All statues are accompanied by direwolves:

While all family members can have tombs in the crypts, statues are traditionally only made for Kings in the North and Lords of Winterfell. The likenesses of these high lords are carved into the stone, some shaggy, some clean shaven. Large stone direwolves curl at their feet.

Because all of the tombs in the crypts are accompanied by statues of the Stark in them and a Direwolf with them as it is on their House banner. You can even see this in the very first episode, "Winter is Coming", as Ned and Robert walk through the crypts.

We also see what appears to be a Direwolf statue later on in Season 5 when Sansa and Petyr are walking through the crypts.

For some reason I can't save an image of the scene above showing the direwolf with high enough quality. However, if you watch the scene you should be able to see what could be one at ~2:46 and what is almost certainly one at ~2:50.

In fact this even has precedent in the books although there the Direwolves are curled around the statues feet.

He led the way between the pillars and Robert followed wordlessly, shivering in the subterranean chill. It was always cold down here. Their footsteps rang off the stones and echoed in the vault overhead as they walked among the dead of House Stark. The Lords of Winterfell watched them pass. Their likenesses were carved into the stones that sealed the tombs. In long rows they sat, blind eyes staring out into eternal darkness, while great stone direwolves curled round their feet. The shifting shadows made the stone figures seem to stir as the living passed by.
