Should I report this dog thats being kept in a trailer?

work for a commercial cleaning company. At one of the buildings I clean, its a construction company, and some of the workers live behind the building in trailers. I have to walk out back to the dumpster everyday, and sometimes I hear barking coming from one of the trailers. I'm not sure if it's hooked to AC or whatever. But even if it was, isn't it still kind of dangerous because the power could go out. I'm just worried about the dog being too hot, or too cold. I can't see the dog, so I can't tell if it's too hot. WIBTA for just reporting it?
