I wouldn't do it.
There are a LOT of dogs in need of homes out there. Leave this one for someone who doesn't have kids and has no intention of having kids. It's really a set up. And no five year old should have to pay for it.
Also, it is unrealistic to live with a five year old and have no situation ever present itself where the dog and the child are in a room together alone. It's too much of a gamble.
