ccl People arn't trying to be negitive the concerns are genuine, it's not just the dog we worry about it's you and your child as well. Most of the responding folks have had years of working around dogs and people . They have seen a lot of the type of situation you are in and how most turned out. I'm not saying you will be one of those you most likely will be the exception . But we are just wanting you to really think out all the possiblities that can happen. I do hope you fond the best match for you.
I will most likely get it from others but a medium dog would be the best for you a Cocker sized Small enough for the apt and yet large enough not to hurt your daughter if she gets knocked down by it.
You should go on the Akc Or ckc sites and see what you can find tht fits your needs in that size .
