Yep. It is terrible those children were killed. No one with any sense would leave a dog alone with a baby. Especially those breeds.
The first account about the pit bull seems just a bit off to me.
Actually, it’s kinda dangerous to leave a pit bull alone with an adult, too:
“Pit bulls are also more likely to kill an adult than a child. In the 3-year period, pit bulls killed more adults (ages 21 and over), 54%, than they did children (ages 11 and younger), 46%. In the 21-54 age group, pit bulls were responsible for 82% (14) of the deaths. The data indicates that pit bulls do not only kill children and senior citizens; they kill men and women in their prime years as well. “
