The dog was a family pet, until it mauled the 17-month-old child. The attack happened at the family's Redondo Beach home.
"The child and the pit bull were in the living room. The child either touched the tail or grabbed the tail of the pit bull. The pit bull turned around and bit the child," said Sgt. Phil Keenan, Redondo Beach Police Dept.
The dog grabbed the child by the face, threw the child to the ground and continued to maul the child, just like it would with a doll.
The child's frantic mother stepped in screaming and yelling at the pit bull.
"The mother was able to disengage the dog from the child and then they called us," said Sgt. Keenan.
The child suffered cuts and lacerations. He was very fortunate he did not lose an eye.
Neighbors of the victims families say their pit bull seemed like a loving animal.
"Jackson is a great dog. Always friendly and always nice. I just don't know. It is just one of those things," said Frank Woleslagle, a neighbor.
"The famous words before every dog bite is, 'Don't worry my dog does not bite. ' And the words after every dog bite is, 'I can't believe he did that, he's never done that before,'" said Sgt. Keenan.
Animal control officials say this pit bull will remain in quarantine for 14 days, and then they will decide what will happen to the animal.
