Well, my dogs don't often run around my house or the yard so I know they could probably live in an apartment. They just need a lot of exercise (walks, off leash time at a near by dog park or field, etc.) away from home. I don't know a whole lot about Boxers but if my Border Collie mix would be able to live in one given the proper exercise requirements I'm pretty sure a Boxer could too. Does Soul's owner have a lot of time to give to her?

Of course, this is just my opinion and others totally disagree with active breeds in apartments.
