Hydrant in orbit

Marmaduke by Brad Anderson, where a fire hydrant becomes so afraid of being gang-pee'd on by a pack of dogs that it obtains sentience and achieves escape velocity and space travel. When i was little I liked reading Marmaduke and i even read the little doggie tales at the end of the Sunday strips.  Then i lost interest in the doggie tales because they were always lame.  Then I lost interest in the strip as it, too, was rather lame. My son likes it though and I'm not going to spoil it for him.
