A jogger who defended herself from a "dog attack" in Anthony Chabot Regional Park was punched and bitten by the dog's owner, according to park police.

The altercation began Thursday morning when the jogger used pepper spray to ward off a dog, police said. The dog's owner confronted the woman and "tackled and punched the victim multiple times," according to the park police's statement.

The attacker allegedly bit the jogger on the forearm, "causing significant wounds" during the struggle on the Goldenrod Trail between the Chabot Equestrian Center and the Oakland City Stables.

The East Bay Regional Park District Police say that the suspect is 18 to 25 years old, described as being of mixed Asian and white race and has a thin build.

The suspect was accompanied by two dogs, police said. One was a "possible Rottweiler mix," while the other was medium to large and had yellow or tan fur.
