I absolutely love dogs I have three at home!
I have one dog! I love selectively bred dogs.
Oh I am not fond of that at all. It's a love hate relationship definitely.
I think it leads to dogs being uniquely attuned. Dont you think?
I guess, but most of the time they are too inbred and it creates problems. Great Danes for example, if improperly bred, suffer from hip problems, digestive issues, and other things.
Yes, I see where you're coming from, but theres also potential for dogs proficient in hunting and herding, pulling loads, 
Yeah I have two blue heelers that herd my neighbors goats, but with the popular Aaron Rodgers commercial the breed will get popular and people won't properly take care of those pups.
Yes that is the unfortunate part, where the influence of human society neglects the needs of dogs.
Definitely, we selfishly put ourselves ahead of other species
I think genetic disorders that affect dogs, often due to selective breeding are because of us
