I am so sorry that you are at this point. I have been there before, and it is agonizing.
The only thing I would ask, have you considered taking him to an acupuncturist? I used to breed Bichons, my Andre had a stroke & was paralyzed, I was going to have to let him go, when I found a veterinary acupuncture clinic - after 2 treatments, he got up & walked, unstable but progress, with subsequent treatments, he later ran and moved with ease. He lived for almost 2 more yrs before he had a very severe stroke that made the decision evident.
It is never easy finding the right time to say goodbye |
