In a tragic story our of Arizona, a trip to grandma’s house turned deadly for one toddler when he was mauled to death by her rottweiler.

The one year old boy and his grandma were playing inside the house. When grandma opened the back door to put something outside, the dog barged in pushing her aside and heading straight to the grandson. Biting down on the toddler, he dragged the boy outside and mauled him, refusing to let the child go. The dog had to be shot by police and was later euthanized.

Rottweilers are one of the most dangerous dog breeds. Their size makes them deadly, and their loyalty, which many owners like, also makes them extremely territorial. I must admit to being somewhat biased against rottweiler. In one year two of the kids in my class needed reconstructive facial surgery after being attacked by rottweilers. (One 4-year-old girl mauled under similar circumstances while visiting her grandma’s house.) But the dog’s sheer determination to get a the boy makes this story especially unique. Needles to say, parents and relatives should be extremely cautious around rottweilers.
