Why our baby got mauled !

These parent should never have been allowed to breed...the pain in his future isn't going to be -his- fault.

Based on the updated description, the parents have now learnt that this is not a good idea in the future. They may not be concerned about this particular dog's temperament, but aren't they teaching the child that it's ok to take things from dogs' mouths in general?

"UPDATE: As I mentioned in the comments that I initially posted with this video, based on our dog's extensive training, temperament, and exceedingly gentle previous interactions with the baby (which are shown in our other videos), under our close supervision, we did not perceive that there was any realistic risk of harm to the baby by allowing her to try to take a bone from the dog. In contrast, a handful of visitors apparently strongly believed that we were putting the baby in imminent danger in this video.

Although I disagreed with those visitors' comments, based on those comments, I contacted the dog's trainer about the video and about the nature of the interaction shown in the video, as the trainer is specifically familiar with our dog's training and temperament. In short, based on her specific experience with our dog and other dogs, the trainer agreed with me that it's unlikely that the dog would harm the baby -- and in her opinion, the dog was not exhibiting any signs of stress or irritation in the video that would lead her to believe that the baby was at any risk of harm during that interaction. That said, she cautioned that a dog's "resource guarding" instinct cannot be 100% bred or trained away, and that a dog's tolerance for someone taking its resources can change over time as the dog develops and ages. Because of that, she cautioned that just because the dog is tolerant of such behavior now does not mean that he'll be so tolerant of such behavior in the coming months. So, particularly while the baby is so young, the trainer conservatively recommended against allowing the baby to take anything from the dog's mouth. Moreover, we intend to follow that recommendation -- so rest assured, we will not allow the baby to interact with the dog again in the way that's shown in this video.

Although I wish the detractors had been a bit more constructive and less alarmist in their comments, I do ultimately appreciate their concern, and I learned a little something from it. So, thank you." from there.

As I see it, the real problem is that regardless of anything else, you don't use an actual infant to test theories about what may or may not be dangerous to an infant.

Do I think this dog would attack this child? No.

Do I think this child could lose a finger because they got it in between the bone and the dog's teeth? Yes.

Just because the dog isn't aggressive doesn't mean the child can't be hurt. Badly.
