If you have visited a dog show lately and seen a small somewhat funny looking dog with what can only be called a monkey's face, you have most likely seen a version of the "Brussels Griffon" breed developed mostly by the Belgians. There are three varieties, almost identical except for coat texture, and since all three varieties can be found within the same litter, it is more appropriate that they should be called varieties rather than separate breeds. However, they are indeed called by separate names: the Griffon Bruxellois , (Brussels Griffon) , the Petite Brabancon, and the Griffon Belge. Their pug like appearance and small size is due to the original crosses of a pug and a King Charles Spaniel with the larger Stable Griffon. They first appeared in 1883, and although some of the original dogs may have been bred by Dutch or German breeders, the majority of the development of the breed appears to have come from the breeders in Belgium.

The bug eyed appearance of the Brussels is due to the large rounded eyes perched above the bracocephalic (foreshortened) nostrils and short muzzle. These facial characteristics lead to problems in hot weather, because dogs with such shortened muzzles appear to have more trouble breathing than breeds with more room in the nasal passages. Also the large eyes can be subject to scratches or even irritations due to the long facial hair surrounding the eyes. The eyes need to be checked daily and washed out frequently. The Brussels Griffon can also be prone to the slipped patella or knee cap associated with some of the other toy breeds. Also, as with any toy breed, owners need to watch that the dog, especially as a puppy, is not allowed to jump from furniture or onto hard surfaces for fear of damage to its small legs.

In the United States, the "Griffs" have increased in popularity as both a show dog and a pet since they were introduced into this country in the mid 1950s. Show classes include both the rough coat and the smooth coated one rather than different varieties in the Toy group. They are now often seen in the conformation ring and more and more as a general family pet and apartment dog. These little dogs are noted for their intelligent and inquisitive nature. The AKC standard calls for a temperament that is "full of self-importance" and that really says it all. Griff owners have found that the Griffon puppy needs to believe that the training is HIS idea...this seems to work well as a training method for this somewhat independent minded little dog. A person who is wanting a small and laid back breed that does not need a lot of attention should definitely not consider the Brussels Griffon, for although they are indeed small, energetic is their middle name. They are inquisitive and have the temperament of a "guard dog", being faithful and loyal to their human families and often intolerant of intruders. However when with their owners and families they are generally sweet and gentle to all visitors. They are very playful and enjoy nothing more than a good play time with children and other small dogs.
