Dogs have co-evolved to live and cooperate with humans for 40,000 years. Hanging out with us all the time is their natural environment, it is their "wilderness". Though i should also point out that you're committing the naturalistic fallacy, ie what is natural (malnutrition, mange, horrible parasite load, being killed by predators, dying due to untreated illness and injurt, being mauled by other dogs, freezing to death, bad water, scavenging carcasses, etc) is good. The concepts of "nature" and "wilderness" are also problematic; for one, dogs and cats are not wild animals. They arr domesticated. They have coevolved with humans to live in human environments under human care.

"Wild" is a problematic concept at best. Wilderness" as popularly conceived of in the west is mostly a racist construction that serves to erase the presence and history of indigenous people. There is not and never has been a "wild" separate from the human domain. We"ve been everywhere on earth for tens of thousands of years. Much of the face of the earth has been influenced and often heavily influenced by human habitation.

Dogs don't share some abstracted notion of freedom and independence with settler brained american libertarians. They're dogs. They want to hang out with humans who treat them well. That's their whole thing. They're fully, completely domesticated, which i suspect many "having pets is immoral" people don't fully comprehend. Frankly I think it's a misapprehension of city people who haven't really spent much time in truly wild places where the wildlife has not acclimated to human presence the way it has in most of America and Europe.

Regardless, this abstract, idealistic notion that dogs "lack agency" is not materialist. It's also not a very strong argument from an idealistic perspective. Most of the time, being domesticated rather than wild animals, feral dogs suffer even shorter, more violent, more miserable lives than wild animals that are at least adapted to their environments. This is because they are dependent on cooperation with humans for their wellbeing. Domestication has made them more playful, less aggressive, much less shy and suspicious and cautious, much more social, given them the nearly unique abilitiy to recognize human gestures and body language, and so forth. Contrast this with wolves, which are genetically speaking a very similar species, and the massive differences in behavior, physical structure, and psychology are stark and impossible to explain away.

Dogs cannot survive and thrive without us (and I'd argue humans are equally lost and miserable without dogs). They have no place in the world except alongside humans. Whatever assertion you're making, what you're defacto asking for is the destruction of the entire species because their mere existence doesn't conform to your idealist notions of agency and independence.

On one hand, I agree, on the other hand, I think forcing people to live without a cat is some kind of war crime
