As long as she's not in pain keep her fed and warm. She may not remember much but she will know she's safe.
We are doing all we can for her, but unfortunately she is in pain. Although she has been loved and had the best of care for 11 years, she must have suffered terribly as a pup and young dog prior to when we adopted her.
She never wanted any affection from us in the past and now if you try to gently touch her face to clean her eyes or just groom her, she goes into a meltdown and has bitten my wife multiple times, the last time hard enough so that I had to take my wife to urgent care the next day due to an infection going up her arm.
Hard to believe that a 11 pound and dropping dust muffin could do that much damage.
We thought that she was at death's door recently, not eating or drinking for 2 days and having convulsions, then she ate and drank the next day and made a miraculous recovery.
Everyone says you will know when it's time, but it's really hard to tell with her.
