She, like the rest of us, is finally showing her age. She is most likely somewhere around 13 - 15 years old and now she has lost her hearing. It is making her timid and skittish and very attached to me. Unfortunately, there is no doggie hearing aid so she is only able to find her way through life by sight, scent and touch. It is easy to startle her now while she is sleeping if you bump her. On the good side, the vacuum does not frighten her any longer. Poor old girl will need lots of TLC!
