The proper and preferred pooping procedure for dogs

I’ve found that my dog waits until the end of the day, until he’s certain that we’re not going to take him for a walk, to poop. I usually walk him in the morning, and he does his thing in the glorious light of the morning sun. However, on days like today, when I happened not to be able to take him for a walk until the evening (on account of our being on vacation), I believe he had all his “stuff” saved up inside of him, holding it all in until he could release it in the wild grass that grows in the parks. Apparently, it is infinitely superior to doo all those dogly dooties in the great outdoors-the great PUBLIC outdoors. Anyone can go in their own back yard! What’s the fun in THAT?!?
I read Travels with Charley by John Steinbeck on our vacation in the homeland of that author, and he writes many observations of his dog. That may have inspired this post.
