Mad Dogs and Englishmen

Stinky Diver, depressed over the fact that his own mother tried ratting him out for a sum of money during the Gulf War, makes friends with an estranged dog, whom he names Smelly. Stinky and Smelly become the best of friends, but the hound makes a habit of injuring the rest of the Action League. Is Smelly just a playful pooch, or is there more to this issue than originally thought?
