My 14 year old Dachshund, Gisela, became very ill. I do not know what caused her problem. My speculation is that she ate the remains of a dead rodent in the backyard, but the veterinarian could not give me a definent answer as to what triggered her condition. She had to be hospitalized and placed on IVs, received numerous tests, sent home with medications, and restricted to a special diet. I was contemplating cancelling my pet insurance policy before this incident since she has been very healthy. It is a good thing I did not do so. She has made a full recovery.
