Hmm a nice idea, Raphael. Perhaps I should start a similar one about cats.

Anyway, let me think of what I like in dogs that cats do not have... hmmm...
- The way they wag the tail when see the owner,
- They are very faithful friends (though many cats are faithfull too - they just too proud to express it more openly and often, lol),
- The way they breathe after an energetic game (e.g. fetching)
Well I need to think of it more, hehe.
