When a dog takes over control

I have to admit it, the Italian version of Kommissar/Inspector Rex is actually better than the original. The stories and acting just seems to have kicked up a notch since Rex moved to Rome.

More importantly, though, I can understand the theme song. I've never been able to quite grasp the theme song for the original. No matter how hard I try, I just can't make out all of the words. It sounds for all the word like this:

I see heroes without fear
Cowabunga, empty streets
Time to hide in dirty cages
Then you'll see how it's gonna be
When a dog takes over control
We'll be fine until the end
That's what they call a good friend
He'll always understand
That's what they call a good friend.

Which, quite frankly, doesn't make as much sense as it could. Particularly the "Cowabunga" bit.

I've tried looking up the lyrics online, but it seems no one else can come up with anything that makes more sense. A few of them have "killing thunder" rather than "cowabunga". So much better.

Is the song suggesting a possible future where dogs are in control and people are imperiled, but thankfully saved by one particular dog who likes us? If so, that really doesn't fit with the TV show at all.

Oh, and then (after Moser was killed and they switched to the second guy) they re-recorded the theme song. Unfortunately, instead of making it easier to understand, they just dropped several lines. Because, you know, that's likely to help.
