Thank you for the comments and questions. And suggestions. Me and miss D put together our clever heads and came up with a poem with words luu-kuu-puu-suu in it. The poem of which I'm very proud of tells that while the moon is up in the sky, in the woods stands a tree under which a bone is hidden. And nothing but a dog's mouth finds it.
Double u, like in the words luu and kuu, is very much like this howling sound we use when we (dogs) miss something or somebody terribly. Wolves are very good in producing this sound.
Rudy, the best way I have found to get people to scratch your tummy, is to use the universal dogs' language in which one throws oneself on the floor and reveals one's belly. Nobody can walk by without scratching a little bit. To get food, I have followed the advice that was given in one of my favorite movies "Homeward Bound" by Disney. (I'm not sure whether it was in the first or the second one.) I strongly recommend it. You should look cute and miserable at the same time. But never slobber, humans dislike it to no end.
This is all today. Oh - almost forgot, one Casino shawl is being knit over here.
