Santa Dog

Santa Dog cost 10 Snowflake Tokens in Santa's Workshop during the Christmas Event 2017, and the event page confirms the price. That token is specific to 2017, and the wiki links it as Snowflake Tokens (2017), separate from the Blue Tokens used for the 2016 workshop pets. The event ended, so trading is the only route to the dog today.

Appearance

The pet is a beige dog sitting down in a Santa costume, with a red and white shirt and a Santa hat. There is no extra text about its behavior or abilities, and the wiki does not give an in-game description for it.

Model source

Its model comes from the limited Roblox shoulder accessory Santa Paws Dog. That makes it one of several event pets built from existing avatar-shop items, in the same way the Elf and the Reindeer from 2016 were built from gear, and not a model made from scratch for the game.

In a trade

Santa Dog is Common. It came from the 2017 workshop, so a trade that says Santa Dog points to that one event.
