Gordon Wharmby (Wesley) often brought his own dog to the set. In two different episodes, Barry was babysitting a dog. In one, the dog managed to get away from him and he and Glenda ran around shouting his name which freaked someone out for some reason. In another episode, he is walking the dog and Smiler who riding a bike in an inebriated state grabs the leash and takes off with the dog. They end up at a bridge where Howard and Smiler dance on the parapet. Wesley drives up with the crew including Barry. The dog barks once causing Howard and Smiler to fall into the water. As a note, I grew up next to a bridge over a creek and I never once hung over the railing and fell in. Like the bridges in Holmfirth, it was a dirt and concrete bridge and so wildflowers grew next to the road.
