Beau is a Löwchen or Little Lion Dog (German: Löwchen, "little lion"; French: Petit chien lion, "little lion dog") is a breed of dog.
The Löwchen once had the dubious distinction, like the Portuguese Water Dog and the Havanese, of being the rarest dog in the world. In 1973 there were only 65 registered examples of the breed. Even today, the breed generally has fewer than a few hundred new registrations each year worldwide
Löwchen's coat is long and flowing and comes in many colours. The coat should not be thin and fluffy like a Bichon Frise, but wavy with a mix of thicker hairs amongst the fine ones. This allows for a flowing coat that is not frizzy or fly-away, and a Löwchen coat should not be harsh like many terriers.
The Löwchen's long and wavy coat is presented in a lion cut. This means that the haunches, back legs, front legs (except 1/2 bracelets around the ankles), and the 1/3–1/2 of the tail closest to the body are shaved, and the rest of the coat is left natural to give the dog the appearance of a male lion.
