Be on the lookout—there's a backwards dog somewhere in the house!

I don't mean to alarm anybody, but Gretsky the dog has spotted a dog in the house. Now, we can't say for sure whether this dog is friendly or aggressive, but it's probably best not to take any chances.

For the time being, this dog—which looks remarkably similar to Gretzky, except that all of its features are on the wrong side of its body—remains on the other side of the glass window, where the backwards house is found. He seemed to be preparing to come through into the house proper, but it looks like Gretzky has succeeded in scaring him away. But for how long?
