Seeing a dog play with a water hose is usually a fun event unless the dog is being filmed by your security camera with the hose inside your house. I’m not sure why the door was left open or the hose was left on but the dog took advantage of both those factors to create his own fun with water inside the house. I love how the other dog just walks on through the room and goes outside like he doesn’t want any part of this. Maybe he told the other dog to knock it off before they all got in trouble.
