I am in the same camp. There was this girl I met on tinder that I always noticed the irony of her rescuing a dog from somewhere only for her to lock it up in a cage for 8-12 hours a day while she is working or partying. It's not right at all.

I have to agree - maybe outside of dogs, all other pets are not happy. For example, how can "fixing" cats be acceptable?! Just because we don't want to allow cats to mate and inconvenience ourselves, we "fix" them and everybody seems okay with it! How is this not animal cruelty by the book?! Cats grow obese and feel miserable. I've had cats, I let them go in and out, they lived fruitful lives and were not forced to come back, yet, they did. During the mating seasons, of course, they were gone for weeks.

There are so many people, and some of us have cats and dogs. Cats kill a lot of birds (and mice and rats—-maybe a good reason to have a cat on a farm) and don’t give much back to the ecosystem. Cat and dog poop adds pollution to land and waterways if not picked up (some is okay, but it doesn’t scale well). I love our dog and feel this non-human person is family. I’m also sad for him not being free to roam and track down deer, elk, bears, coyotes, and potentially end up injured or dead. We run with him often, set boundaries, share affection, and I’m not sure I want to subject another animal to this captivity after he dies. I’d like to switch to helping the land I’m on be more diverse and robust, with healthier soil, more insects, more birds, more mammals (with measures taken to keep rodents out of the house), and to spend time observing this as a way to get me outside.

why is this different for dogs?

I have been bothered at times at just how outside the overton window the idea that animals/pets, dog or cats should be able to e.g. see their parents or children, ever again, falls. I'm not a vegan or a big animal person, but it just isn't talked about.

Well, you're right. Dogs are emotional, and get attached to people and happy, but it's only because they don't realize how miserable they actually are and simply don't know any better. I personally like dog breeds closest to wolves like the German Shepherd. And I pity some of the breeds resulting from ages of selective breeding, which don't even resemble dogs.
