Black and White Minature Australian Shepherd missing. He is a little over 6 years old and does not do well with fireworks. The last I had seen of him was last night when he left the living room to go into the bedroom due to the fireworks. I had given my other dogs an opportunity to go outside to take of care of business around 11 pm and he didn’t follow but not in the home this morning. I have a locked gate in backyard so not sure what has occurred so this is a long shot.
