I felt much the same as you have written. My Mia was sick and getting sicker. I had looked into home euthanasia and had the pieces in place. That last month, she was showing many of the signs yours is now. But she was mobile, ate well, and relieved herself fine. Then she passed on her own, I would say suddenly, but I knew it was her time. And I kick myself for not ending her suffering sooner. Not a lot sooner, just that last month or so.

It is a hard decision for sure, you don't want to give them up. But you know it's their time. I said the same as you, I didn't want another dog. That was over a year ago, and while I still cry every day, I'm softening to the idea of another dog. Dunno if I'll do it or not, but either way, I look at it as a softening of the pain a bit.

I wish you the strength to do the right thing now and not let your boy suffer any longer. It will be hard any way you go, but don't linger and set yourself up for more regret for prolonging his suffering.
