Pets usually can't wait to get outside. They're clamouring for you to open the door and let them out. There's gardens to explore, people to see, business to take care of!
Sometimes, they're just as eager to come back indoors! They don't like the weather (rain! snow!). They meet an unwelcomed visitor (scary wildlife!) or they know it's dinner time. At this point, they're going to do whatever it takes for you to let them in!
