Agree with all the comments so far.
The thing that struck me, is that these folks didn't seem to have an ounce of common sense, let alone any dog experience, or knowledge of dog body language (head shake).
And the Rescue, whom I'm assuming has some such experience, apparently did nothing to educate this family about much of anything in regards to dog safety, child safety, and how to deal with this dog (who was probably stressed and nervous in a new environment) when first bringing her home.
What on earth were they thinking of ???
Who in their right mind, lets a 2 year old (or any age for that matter of fact) child, crawl face first right into the face of a strange dog that you just brought home? That child is very very lucky, that he was not grabbed by the head, face, or throat.
And they call the dog 'crazed'?
I would hold that Rescue responsible for not educating the family , and hold the parents responsible for not educating themselves, and not teaching their child how to interact with a dog (any dog) especially a strange dog.
In regards to the breed, I have met several American Bulldogs. They actually make wonderful family dogs. They are loyal, playful, goofy, tolerant of children, protective of their home and family, and if properly socialized, are friendly as well. BUT, these are large, powerful dogs, and who knows what the background of this particular dog has been: abandoned, surrendered, abused, neglected, used for dog fighting??? Who knows....
Just sad all the way around.
