You did not mention age, but did mention she get her dog neutered, and from the tone of your post it came off as something she, and everyone else should do asap. The title of the post states that her dog is only a year old, which is 6-12 months too young. And yes, neutering eliminates testosterone, that's just a scientific fact, but testosterone alone is not the cause of most canine aggression. The majority of aggression is behavioral not hormonal. So what happens when you advise someone at your vet's office to neuter their dog to avoid aggression and their dog becomes aggressive anyways? They usually end up in a shelter, and with behavioral aggression they will more than likely be put down.
Also, if you had thoroughly read the thread here you would realize that the conclusion is that her child was not bitten but scratched in a bout of playfulness.
Health concerns should always be a top concern for someone whether they have an intact male being aggressive or a calm and relaxed altered dog. Health should always, and I mean always be number one. Someone that holds their dog's health in high standards is going to notice behavioral issues and handle them correctly, not just blame it on a pair of balls and call it good.
