I am so sorry you are going through this. My little girl, Ashley, suffered from Canine Cognitive Dysfunction the last year of her life. She was very close to seventeen when she passed away. We agonized over whether we were doing the right thing for Ashley by keeping her alive. We saw her doctor every two months, often more often, and I always asked him to tell me if he felt her quality of life was low. He really felt, with the help of Anipryl, that she was still a happy little girl. He told me that Ashley was still very responsive to me, and that was a good sign. The Anipryl was not a Miracle drug, but it helped my little girl, enough that her anxiety, confusion, and pacing were better controlled. If I can be of any help, please let me know.
This thread is very long, but it has a lot of useful information.
