Chet and Chem

Chet and Chem are twin canines that started out as a pair of Poochyena.

Now they are anthro shapeshifters that love to take many different forms. However, no matter how far they are from each other, when one takes a form, the other twin feels the draw to take the matching form. Resisting that desire is not impossible, but gets gradually more uncomfortable on both parties until one of them caves and matches their form to the other one. (Changing to a different form will lessen the need to match for a short moment, but it will gradually intensify again)

Chem is usually the one that transforms first in a situation.
