As a Mastiff person, I am sad this has to end this way for the dog but unfortunately because of the circumstances, it needs to. I only hope these type of tragedies are a wake-up call for ALL dog owners that young children MUST be 100% supervised when around dogs. And frankly, because it takes so little from a dog to cause serious injuries/death to young children, I would personally restrict a child from close contact with a dog.
