My baby, Gracie, is still confined to my office/den with me while I work/read. We couldn't find an inexpensive gate to fit the doorway so my husband rigged up a plexiglas barrier that I can step over but the puppie can't get over. When it starts getting dark at night and I have light on in the room but the hallway is dark, she sees her reflection and goes crazy - barking, growling, trying to attack it. We call her reflection the 'evil puppy' who comes out every night to scare her
I put a towel over the glass to calm her down, but every night we go through the 'scary evil puppy' routine for a few minutes. She'll look over the top and the 'evil puppy' isn't there and she can't figure out where it goes. It's hysterical.
