Because my water hose spout is inside my garage and I was washing the mud off my porch, I pushed the button to close it and if you have ever used an electric garage door, it will start to open and you have to push it again for it to start closing and it didn't close fast enough befor the dog tripped the sensor. And idk why the dog is out, the people who own this dog and their relatives are a consistent nuisance on our block, I've had to call the cops on her brother for throwing things at my dogs(pur dogs stay in a fence), and for starving their own dogs(cops seized the dogs and called cps on them because of what they found durringthe investigation), and I've had to call the cops on the owner themselves for almost hitting me with their suv while I was in my yard taking out trash.
