If a dog escaped through a broken fence defective gate, or unsecured enclosure before attacking someone, the condition of that barrier may become important evidence. Was the owner aware the dog could escape? Had it escaped before? Was the gate routinely left open or unable to latch properly? Photographs and measurements of the property can help show how the dog got loose and whether the attack could have been prevented. I am Pennsylvania dog attack attorney Jeff Pennys.
