Looking for a small dog as a pet in a flat.?

Hi everyone. I live in a smallish flat and I really want to have a pet dog. Ive been searching Bahrain and so far all the dogs at the BSPCA etc are larger type dogs. I really need a small dog so it has some space to move around.

If anyone in Bahrain has a small dog/puppy that will stay terrier size etc and is looking to home it...or if you know of where I can get one I would appreciate a heads up. I prefer to take one free of charge as I dont like the idea of buying pets off of people...but will decide that if something comes up.

Thanks alot.
