WWE has added a rather unusual stipulation to upcoming SmackDown matches between Roman Reigns and King Corbin.

Roman Reigns and King Corbin have been feuding on Friday Night SmackDown for a couple of months now, and it looks like the two will be in a storyline together until at least after the Royal Rumble.

Throughout the storyline so far, several dog references have been made, whether it be Corbin pouring dog food over Reigns, or a man coming out dressed as a dog in reference to The Big Dog.

It looks like those dog references are set to continue into February at least if advertisements for upcoming SmackDown events at the start of that month are anything to go by.

Reigns will take on Corbin in matches at the SAP Center in San Jose on February 7 and at the Rogers Arena in Vancouver on February 14.

According to NoDQ, in both of those matches, they are being advertised with the stipulation that the loser must eat dog food. That's right, the loser must eat dog food.

There's a strong chance these matches just end up being dark matches shown to the live audience after SmackDown goes off the air, but one of the matches could end up on TV as well.

Dog food has been heavily associated with the feud between Reigns and Corbin so far, so it wouldn't be surprising to see it still part of the feud if the two are still part of a storyline after the Royal Rumble.

The Big Dog is currently one of the favourites to win the men's Royal Rumble match next month, so it wouldn't be surprising to see him still feud with the King of the Ring winner after the event in order to keep him occupied until WrestleMania arrives in April.

However, there will be some fans hoping these two matches will be one of the final times Reigns and Corbin have a match against each other in the ring for some time in order to freshen things up on SmackDown.
