Every dog must have his day, but this trick gives you the Day of the Dogs. To turn every member of your current fighting group into Jogurt (the dog; not the dairy product), do the following:

Get Jogurt (the dog) to join your team.
Make him kill someone. When you do this Jogurt will receive a ring.
Equip whomever you want to be a dog with the ring.
Transfer the ring to the next person to be a dog.
Repeat steps 3 and 4 until you have everyone in your group is a dog.
Enter a battle to let slip the dogs of war.

Note: This trick lasts for one battle.
