I have no more advice to give on this except to say choose the breed carfully you don't necessisarly need the baddest dog in town, you have children and if your not experianced with some of these breeds it could turn out going very wrong dispite all the flowery rederic you read on breeders web sites. Rember they want to sell a dog. Please becarful. I attempted to suggest somthing that would give you the best of both worlds.
