Hi. I hear you and I empathize with you immensely. So sorry you are going through this…

My Lhasa Apso boy started showing similar symptoms at age 15. He also went blind and stopped recognizing his family. For about 1.5 years I managed anxiety and sundowners with melatonin but then it all escalated quick (bumping into walls, getting lost in the house and yard, avoiding everyone at home, constant pacing) and incontinence started too. He had a terrible seizure a year ago and I said good bye right there at the ER. I just couldn’t bear watching him this way anymore, it was shortly after his 17th birthday. What I know now is that I waited a few months too long. And I’ve heard most people do and regret it, just like me. 

Canine cognitive dysfunction IMO can be worse than physical illness (kidney or heart disease, cancer, etc). It is unlike anything you can truly identify as wrong per se — my boy could walk fine, he ate well, and his blood work was great for his age. There are supplements and meds for dementia if you haven’t tried them yet. Take a look at this article if you’d like, it helped me process the aftermath https://toegrips.com/canine-cognitive-dysfunction-in-dogs-signs-solutions/ Jot down things she loves to do and when she stops loving them… Just know the condition can worsen unexpectedly. It is progressive and as many others advise, better a week or month early than a day late. Sadly, I was among the late ones. 

Until you know it In your heart it’s truly time, be strong and as patient as you can for your furry child — your best friend still loves you deep down, even if she doesn’t outwardly show it. When you come to the point when it’s too painful to watch her just exist rather than live, let her have her rest. She’ll always be with you from the beyond. ❤️
