Courage the Cowardly Dog is a pretty strange show. Not a whole lot of stuff that happens in the show makes any sense, even when you consider the fact that it's a cartoon. But why is that? One of the many fan theories about Courage the Cowardly Dog that sets out to explain this is from Redditor DiggaDoug492, and this user provides a pretty compelling answer: everything in the show is happening from Courage's perspective, i.e., a small, cowardly dog is seeing weird stuff go down because that's how he views the world.
In fact, there's actually quite a bit of evidence to support this theory, and SirDiego reinforces it with some salient points of his own on the same thread. What's more, the show's intro might even be able to prove this theory all on its own.
Take a look at the breakdown of this Courage the Cowardly Dog fan theory and decide for yourself.
Freaky Fred Is Clearly Just A Weird Dude
...Which Is Why Courage's Owners Don't Fear Any Of The Villains
The monsters in the show usually have a rather human-like appearance, the only difference is that they tend to have super creepy deformities. Courage always freaks out when he sees these creatures, but his owners tend to interact with them as if they are indeed just normal people.

The Stitch Sisters are a great example of people who Courage sees as being monsters, but who are actually just people. The likely truth in this case is that they are simply twins, but because Courage has trouble comprehending that, he sees a two-headed being instead.
Courage Protects His Owners
If you've ever had a run in with a reactive dog, you know that they don't like it when strange people get too close, and that's often because they feel that they need to protect their owner. Courage is no different. He imagines himself thwarting these monsters and protecting his owners because he believes that this is his job.
