So I recently adopted a chihuahua and the family who had her before me were in their 80s. The man was hospitalized and the dog had been left alone for several months. His daughter would come and feed her but for the most part she was alone and sometimes outside for extended periods. So now when I leave for work or even leave the room she just loses her little mind. So my question is what can I do to help her with this separation anxiety? She also seems to be afraid of almost everything.
