The Löwchen is breed of dog that once had the dubious distinction, like the Portuguese Water Dog and the Havanese, of being the rarest dog in the world. Even today, the breed generally has fewer than a few hundred new registrations each year worldwide.
The head of the Löwchen is one of the most important features, with its short, wide muzzle, broad skull, lively round eyes, and pendulant ears. The head, when in proportion to the body, is neither too big nor too small, but helps to emphasize the friendly, regal, and leonine personality of the Löwchen.
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 neither be soft like a nor harsh like many terriers. They can come in all colours, including brown, that allow for dark eyes and nose.
It is an old breed type, found in many countries as far back as the 1500s. The modern sources of the breed were from Belgium, France and Germany enthusiasts in the late 19th century.
