On paper, I'm the worst dog owner ever. I live in a 400sq foot apartment with no yard. Have one coydog (coyote dog hybrid), and one intact male whom I have no inention of neutering.
Yet, somehow, I've managed to foster puppues and adults with amazing resultss. I've had shelties, shar-peis, shibas, dachsunds and everything in between. If you want to make it work, you will. If you don't, don't bother getting the dog in the first place.
Rescue is hard, and its easy to be jaded. My current foster is 2, and has been in 3 homes. He's a difficult breed, and I will be careful of where I place him, but apartment living is the least of my concerns with him.
