We have found a few that we thought might work, but a couple of them (Pia the cattle dog and Speckles the blue heeler) are probably too energetic to be in an apartment. We've also considered Sasha the chow chow / keeshond mix.But we're unlikely to get one of those. One of the breeds of dogs we've found that we think would work is a Shiba Inu (pictured). They've had a few at the humane societies, so we're hoping they get another one at some point.
On a future note, I am looking forward to getting a house and (hopefully) a big outside dog. My two favorite types of dogs are the St. Bernard and Siberian Husky. The humane societies also currently have a very cool Alaskan Malamute.
I am, of course, still a cat person, but my wife is allergic. I have hopes of either a future hypoallergenic cat (when they're not $4000) and/or an outside cat, when we get a house.
