This story covers a pup which is abandoned by his parents long time ago in an Animal clinic. Though the dog is really not abandoned but he is the only animal who has escaped in the hands of the evil veterinarian. His parents were used for experiments and been sent to the moon and never to be seen again. In an alley were trash is being dumped, courage stayed and cried. Muriel, an old lady with a warm heart, noticed this dog alone with no one to comfort him. He picked up the dog along with his husband Eustace and began to go home in their house in the middle of the dessert.

Courage has been treated like one of the family but for Muriel's husband, courage, treated as a slave. Here began courage's adventures. Since the place is in the middle of nowhere, it has been know to be the landing point of aliens. Week by week, Aliens came, attacking and trying to use Muriel and Eustace for human experiment, but with courage around, it never happened. Courage may be a coward dog, but with everything that Muriel has given and showed him, he never gave up protecting the two from the hands of aliens. Thus, resulting to a never ending battle between aliens.

The Cartoon TV series focused on what the dog Courage can do to protect his foster parents from being abducted by aliens. Many types of alien had tried to use Muriel and Eustace for human experiment and some tried to eat them. Sometimes alien may not be harmful but the fact that in one mistake, they can cause major damages to the planet. Sometimes, these aliens transform themselves into animals or into human itself, to disguise and not be recognized. Courage is a real expert when it comes to alien, he can distinguish the alien from its copied form. Aliens who lived underground, even live Eggplants become Courage's enemy. But not all of his enemies were aliens, there were strange human beings which introduce themselves as a salesman or a newscaster but in the end, all of there motives seems to be revealed when Courage is on the job.

Each series of courage the cowardly dog is really fascinating. It makes me wonder how Courage figure out ways to defeat his enemies. A dog with a Huge brain and brilliant too, thats how I see courage in each series. I really enjoy watching this cartoon series on DVD while eating popcorn and seating in a soft couch, though Courage the cowardly dog is played in Cartoon network, i enjoy it more in a DVD because I can watch most of the series twice a day or more.
