I am so sorry to read (hear) about this. Bubby was a real person I believe, and most dogs are not really above the animal level, some do make it there. I guess it has to be a natural occurance to merely chance upon such a relationship, it cannot be sought out and made to happen by will power.
This happened to me when I was 5, on a visit to friends in Oregon, a commune in the mountauins around Portland on which people built yurts and geo. domes to live in. A wonderful and love filled small dog attached to me and played and traveled the forrest all day, after a week we left to come back to Ca. and I never saw him again, but I will never forget him, I will see him in heaven, I hope.
(insert bible verse here, but can't remember what it is)
My mother is quite literate, she reads the best literature ever published and has for most of her life. As I read your post I became impressed with your construction of text (none too crudely stated I hope). So, I copied your text into ms_word, used it's functions to edit and change the font, got it all onto two pages and printed it for her to read and believe me, she was very very impressed. That IS saying something.
Your writing quality is worth publishing, which could become a source for your wife's medical bills and further.
So, thank you for the reminder of some possibilities that happen from humanity, as there isn't much of it in my town, at least not at your level.
