I’ll say it again.
Truth is, this hardly ever really happens. Except with certain types.
You can bet most kids are behaving these ways. Yet we don’t see millions of reports of dog attacks/maulings/killings.
With two of four dogs, three of the dogs bit the face of children including one when I was 3 years old. All four were mutts.
My bite required stitches. The other was a neighbor kid and he had a welt on his face and the third was another neighbor. Was it life or death? No but it is foolish to assume that a dog will not bite just because is a nondescript breed.
