That study about chiahuahuas being one of the most aggressive breeds is right. They get extremely antsy and aggressive around strangers, especially other dogs and children. They're not the sort of dog you can just walk up to and pet. Luckily, mine has only resorted to barking for aggression, and I've been training her off that.
I have a chiahuahua. He barks a lot around strangers, but never attacks or is aggressive. In fact he is quite coward. And the fact that is the old breed that the skull never closes makes them quite fragile. I doubt any chiahuahua can affort to attack even a very small child.
I choose it because the breed is the smallest one and my boy was at the same time afraid of dogs and wanting a dog. The breeders tried to tell me that this breed is not the best for childs but not because the dog can hurt the child but the child can hurt the dog easily. But everything went well and when my second child comes home some months ago the dog was extremely calm around her, never even barking.
