Family seeks owner of dog that attacked elderly Antioch man, killed his dog

By Amanda Davis

I wanted to reach out about a devastating dog attack that happened to my family on Sunday, November 2, 2025, in Antioch. My 73-year-old father was severely injured by three loose dogs, and our small family dog was killed during the attack near Greystone Drive and Rockford Drive, close to John Muir Elementary.

Antioch Animal Services (Case #25-9756) is actively investigating, but the police have not received cooperation from the homeowners believed to own the dogs involved. Furthermore, the flyers (pic attached) we have posted in the neighborhood have been torn down, which feels very intentional. We are desperately trying to locate the owners and are hoping that some news coverage might encourage witnesses or neighbors to come forward with information.

My father had surgery on 11/13 because of his injuries and had to stay in the hospital for the night for monitoring.

Our family is heartbroken and doing everything we can to help Animal Services find the truth.

This story is about accountability and public safety, as the dogs are still unaccounted for and we do not want another family to suffer like ours has.

Here are the factual details of the incident.

  • The attack occurred on Sunday, November 2, 2025, at approximately 8:15 AM near the intersection of Greystone Drive and Rockford Drive in the Eagleridge neighborhood of Antioch.
  • My father, Jim Thomson, was walking his small dog, Benji, on leash.
  • Three large dogs came up from behind with no owner present and attacked Benji.
  • My father fell into the street during the attack and later required surgery for a fractured elbow.
  • Nearby residents intervened and assisted my father by calling 911. He was transported via ambulance to Kaiser Sand Creek.
  • Witnesses described the dogs as one husky, one Belgian Malinois, and a third dog that may have been a shepherd mix. They ran off after the attack and were seen by multiple people in the neighborhood including the paramedics transporting Jim to the hospital. 
  • Candy Thomson, Jim’s wife, transported Benji, with the help of a neighbor to VCA, the emergency vet, on Sunset Drive where Benji died from his injuries.
  • Several neighbors have already provided helpful information, and we are hoping that anyone with additional details or security camera footage from approximately 8 to 9 AM on 11/2 will come forward.
  • Animal Control is currently investigating. Jessica Knittel is our contact.

If you have any information about the attack or name of the owner please contact Antioch Animal Services at (925) 779-6989 or his daughter at (213) 361-5407.
