Yesterday we were in our minvan (I had not entered yet and was standing outside the fornt passenger door but wife, children, and dog were inside. My daughter mashed the button to close the power sliding door on the right side of the van but did not notice that the dogs tail was wagging near the door entrance. All of a sudden I heard loud screaming and I opened the door on the right side. She was bleeding and in tears and said that the power door had closed on our dog's tail. I am a physician so I provided first aid. My concern is that when we bought the van we aksed about the power doors because we were concerned about them possibly closing on someone or something since they can be closed by multiple passengers. The salesmen assured us that the doors would not close on anything or anyone and would reverse if they met any resistance. Well the door completely closed all the way in this case despite the dogs tail sticking out of it.
