I guess it should have dogs, if it is handled like the first two episodes. 201 had Santa in it and Santa also being the word that had been changed from the original title. In 202 Mo' had been substituted by Moai and it contained Moai head statues.
So, since episode 3 is called "Chariots of the Dogs" and the book the title is refering to is called "Chariots of the Gods", it is likely that 203 will indeed contain dogs. I'm not sure if the chariots would be mandatory. I wouldn't have called Santa's hut on the northpole an ice station either..
