Specialty Magic: Students may have up to 1 magic classification from 1 to 4 AND YOUR PET MUST HAVE THE SAME MAGIC TYPE! The students will select a young pet from the Pet Store after arriving at the Academy. Draconic Teacher may have up to 3 magic classifications and a full grown dragon.

This was what I was referring to. Magic classification must be the same as pet, and I can have any of the four elements, but my pet must have the same. This was my understanding, correct me if I'm wrong. So I was wondering which of the four classifications available corresponds to the Arcane Hound.
