Dream of person, screaming, children

Its evening time just got dark my husband yells out the house door to tell me about a person breaking into houses taking children and giving it to a vicious dog to use as a toy and tells me to go a few houses down to tell a family friend what is going on. I see myslef running crying and screaming ashley and they turn the radio up and run inside the house. After I have made sure she knows I turn around to go back home and In the process of doing so the dog comes out of no where and attacks my arm. Latched to my arm the dog is just sitting there and a officer shows up shoots the dog in the side of the head
