Such an interesting article.
We are currently living this with our darling 12 and 1/2 year old Iggie girl Tari, and it's so hard.
I think it started about 6 months ago. Previously, if anxious, eg storms, she could always be comforted. But now it's heartbreaking to watch as she suffers such terrible anxiety - involuntary jerking, bucking, body twitches, pacing, constantly following us and jumping up onto our laps and down again over and over, clawing up at our legs if we're standing, scratching at doors, jumping dangerously over furniture, etc and nothing can comfort her. This can go on for hours. It's hard to believe such a tiny little body can continue with such non stop frantic hyperactivity for so long. It's as if she's possessed!
It first happened just at night, but is now happening all day as well. Initially, under our vet's supervision, 1/4 tablet of alprazolam (same as xanax) did the trick, just enough to enable her to relax, and us to sleep, and things improved. But things deteriorated and soon 1 tablet each night was needed. Once again things improved, and we had almost a month of calm nights - bliss, as I was so sleep deprived. I was sitting up with her to enable others to sleep.
Now it has escalated and we are at the limit of 1 tablet each 8 hours. It is only giving her relief for 5-6 hours and then I have to sit with her 'til she can have the next dose. It's so day to day and all so hit and miss. Sometimes she will relax within 1/2 to 3/4 hour of having the tablet, other times it takes 2 hours!
It's so distressing and heartbreaking to see her like this.
Even though our vet has mentioned Canine Cognitive Dysfunction - this article has shed light on the sad reality, interesting the progress is so much quicker, we may have to face a very sad and tough decision at some point. During her "normal" hours she is quite good, enjoying a walk , has a spring in her step and plays a little bit with the other dogs, but as soon as she starts clinging to us, and the bucking and involuntary body jerks start we know her anxiety is taking over.
Sorry for the essay! This is something we have never experienced and had no idea how severe it can be.
