Zenobia,
You aren't making a mistake here. You are doing the most compassionate thing for this little member of your family.
My heart goes out to your family for this loss. You've given him a great life and done more than most ppl would have. In his mood change he's letting you know that he isn't fully here any longer. You're a perceptive owner to pick up on his cues.
Bless you for loving this dog for this time you were lucky enough to spend with him.
(((((((((Zenobia)))))))))) tears are okay with losses. Anyone who says otherwise or gives you any gruff you just send to me and I'll take care of them. There's this cousin Guido that has been offered up for me and I'll contract him out for this kind of work

I'm so protective of people after animal loss........the public at large tends to not understand this kind of thing and that really chaps my hide!!
