At the very end, Nevada was getting stuck in small places & crying for me to get her out. She looked lost. I think she had some Neuro issues going on due to the Cushings Disease. She also had to be reminded to eat & once started- to continue to eat. She began falling. It was sad. I'm sure there were dementia issues going on at 15+ years old. I didn't have her PTS because of any inconvience, it was due to I couldn't keep her safe and she was hurting herself. I did it out of love...
