What are some good small to medium dog breeds?

I live in a 2 bedroom inner suburb unit with a small backyard but I really want a dog. I am willing to walk it from a half hour – and hour a day. Obviously I will only be getting a small to medium sized dog otherwise it would be cruel. I would like a dog that I will be able to train, doesn’t bark much, it dog and child friendly and doesn’t have too many potential health issues. Any ideas?
