Dog is a sheepdog featured in the Slime is of the Essence Treasure Hunter promotional event. He belongs to John, of whom he can usually be found in close proximity to.
On each day of the event, Dog could be found doing the following:
- On the first day, he stood near the King Slime along with his owner, John.
- On the second day, Dog barked down the well to draw attention to those that had fallen down it.
- He disappeared along with his owner on the third day of the event.
- On the fourth day, he chased Slippy around Rimmington.
- On the fifth and final day, he disappeared once again together with his owner.
- For a week after the event, John and Dog talked about going home.
He can also be found at the pet parade during the Summer Skill Off and Winter Chill Off.
- John, along with his dog, contain multiple references to the film franchise and its main character, John Wick. His nameless dog alludes to the titular character not naming his dogs in order to prevent emotional attachment.
