A Northern California woman says her Chihuahua died protecting her children from two pit bulls that got into her apartment.

Mayda Estrella, of Richmond, says the family’s Chihuahua, named Manchas, jumped in between the canine invaders and her 4-year-old son Sunday. A pit bull grabbed Manchas with its jaws and carried the Chihuahua away.

Contra Costa County animal services officials say the Chihuahua was killed, and the pit bulls are now in custody.

The pit bulls’ owner says they had escaped their yard by chewing through a fence. Estrella says her front door was open when the dogs came in.
