Many stations have a dog that hangs around the weather office and many dogs end up going on air. But, of course, sometimes the dog gets underfoot, or has an accident in the studio (you know just like the floor crew occasionally does) and you have to keep an eye on the pooch around the station.
So, WPVI ion Philly showed off the power of their weather graphics and they added a puppy. But this dog is not one you have to worry about peeing on the floor director's leg.
Although if you watch closely, you notice the dog has a few glitches.
