I am not sure how to deal with this or why it's suddenly happening, but Daisy is becoming more and more afraid of things. Usually, it's stuff like bags or boxes. Today I took her with me to get her food and she just about slipped her collar trying to get away from a box that they had by the door to collect dog food donations for shelters. I'm not sure why this happens and I don't know how to treat it. Then, when we got home I put her bag of food down and she barked at it like it was going to come after her. If I even tried to move it, she would shake like the bag was going to smother her. Any ideas on how to work with her on this?
