They are all varieties of the same breed, with a variation in color. The reddish one is called Brussels Griffon (or Griffon Bruxellois), and the black one is called Belgian Griffon (or Griffon Belge). Hot Shot is a proud father of some puppies, they are black though, unlike himself, and therefore called Belgian Griffon. You might find this breed with short tails too, they are docked in other countries, but that isn't legal in Scandinavia anymore. In the United States it's also common to crop their ears, which will give them a different look.
Hot Shot is also pretty succesful at dog shows, he holds the titles Swedish, Norwegian, Finnish and Nordic Champion as of now. Sake has also became a champion, he is Swedish and Finnish champion, and Sune has yet to become one, but he has a cert from Finland now.
Hot Shot's father is American and his name is Windtrotter's Billy Boy, and he's a pretty wellknown Griffon, since he has won alot of titles. And he is also said to watch TV, and that is something Hot Shot likes to do too, he really loves it. The others don't care much about the TV, they have other things to do, and Sune is always up to some mischief.
Now they have their very own website also with lots of pics and info! Check it out here!
