Factual background
Diane Wolf and her husband were walking their dog on a trail in Tilden Regional Park on Oct. 6, 2016, in an area in which dogs are allowed to be off their leashes but only when the dogs are under their owners’ control. Alexander Weber was also walking along the trail with his dog, a Boxer-Argentinian Mastiff mix, and a friend, Martin Cenek. Neither of the dogs was wearing leashes. Both groups were near the end of the trail, and Weber and his friend were approximately 70 feet ahead of Wolf and her husband. Weber’s dog started to lag behind his owner and then turned and headed towards Wolf, her husband, and her dog. Wolf yelled that she was afraid, and Weber tried to get his dog to return by yelling at him to sit. However, his dog did not obey. Weber called him several times, and his dog started to return to him. Wolf was scared and turned around and started to run when she felt something hit her in the back of the knee. She fell and broke two bones in her leg and dislocated her ankle.
