Yeah actually they did. I think it's because when I first used the lcicker with each of the dogs the first thing I did was just click and then give them a treat so that they would associate the click meant a good thing and even before I used the clicker they knew what the praise words meant.

For the praise words I always use either "YES" or "GOOD DOG" in a really happy voice, and they all know what it means when they hear it .
