Hope this works.
Miss Bessie was 10 years and 1 month old when we took her into rescue. She was so neurotic her owners had her at the veterinary psychiatrist and I received a 70 (seventy) page treatment plan for her. She's a product of divorce and staying at various family homes for a month or two at a time from the age of 2 on. We've had her just over 4 years. The longest she's ever been anywhere. She no longer trembles when we get into the car(I guess she knows she's not being given away again).
