The Warning Signs
In the beginning, Miller failed to notice that Crosby changed. At home, they did not change their routines. This only made it even harder to identify the warning signs. But it finally hit him one day as he returned home after a long day at work. He expected Crosby to welcome him into the house, but he was instead greeted by a shocking sight. Miller had no idea what he was looking at and felt disturbed by it.
Looking At The Wall
Miller tried calling out to Crosby, but he did not get a response. Confused, he looked around until he saw that his dog was staring at a wall in the living room. He initially assumed that the poor dog had bad hearing since it did not respond even when he spoke more loudly. Miller came up to his furry pal and checked out the part of the wall that the dog was fixated at. He could not see what was so interesting about it.
