When people say that dogs have personalities and are expressive, non-dog-owners do not really believe. We lucky dog-owners, however, know better. Dogs are very good at showing their humans how they feel.
For example, look at Shio's expression as T put a costume on him...
Regardless of whether he enjoyed being dressed up or not, we had to bring him to the dog run Howl-O-Ween party as Robin Hood!
See the resemblance?
We found his Maid Marian there too! (Did not plan it... I swear!)
