My little girl, Ashley, had Canine Cognitive Dysfunction the last year of her life. Anipryl helped ease her anxiety a great deal, but she had many symptoms similar to dementia. She passed away close to her seventeenth birthday. It was difficult to care for her, but I wouldn't have given up a second of the time we had with her. If you have any questions, please don't hesitate to ask. The link to the thread below might be helpful to read. It's very long, but it's also very informative. I wish you many more joyful and loving moments with Tootsie. Each moment with our little ones so so priceless.
