We all tend to humanize our relationships with dogs, especially because so many of them are very loyal and are great companions.
But with maturity, a lot of dog owners do reach a good understanding of how to care for and treat a dog. With my last dog, i put her health first, fed her responsibly and made sure she was consistently clean and comfortable. Yes, I have a large house, and she had the entire run of it - meaning sometimes I didn't know where she was even though I knew she was in the house - but she was a very well behaved dog and it made her part of the family.
I did do a lot of reading of Temple Grandin's work on animal behavior and as to how animals and dogs think. This really put a stop to the humanization on my part of my dog. I wanted her to be a dog, and was grateful, for example, even though not apparent, that her greatest form of affection was simply to press up against us. It was the denning instinct in play, and we just let it happen without a lot of fanfare or dog talk and the like. Dogs also like consistency - so we took care to keep the environment in the room she most often slept in constant. It gave her a sense of comfort (Grandin has done an experiment where she put a briefcase (a briefcase!) in the middle of a bunch of cattle and recorded how much it distressed them). The point is that not all dog owners, especially ones that have been through a few, humanize their dogs in a selfish way.
I had a great trust relationship with my dog, and I miss her, but of course, I don't conflate that with any human relationships. Like anything else, you get out of what you put into it - and dogs can be rewarding.
