Is it right to keep a pet?

other people have talked about this but i dont think that owning pets is inherently immoral. owning pets is a net good for both you and the pet, generally.

I want an animal friend but i also know that animals don't feel about me as i feel about them.

Most common pets like humans. Animals that don't like humans generally aren't kept as pets, right? I don't know about like, lizards or bunnies or anything, though.

However, I also started feeling bad and wondering if the dogs were really happy living in a small house with a not that big yard.

I suppose that big dogs wouldn't like living in small homes with no outside area to play in. But small/medium sized dogs would suit small houses/outside areas fine, especially so if you take them for walks often. I don't know about keeping a dog if you're in like a studio or 1br apartment, though. You would have to talk to people at the shelter or pet store.
