Papillons are prone to patellar luxation (common in small breeds) and dental crowding leading to periodontal disease given their small jaw. As with many toy breeds, puppies can be prone to hypoglycemia, so frequent small meals matter early on.
Small, measured portions of a quality small-breed diet; frequent feeding for puppies given hypoglycemia risk.
The long, silky single coat (no undercoat) is surprisingly low-shedding for its length and needs regular brushing to prevent tangles, especially around the signature ear fringing.
Highly intelligent and trainable, Papillons do well with positive reinforcement and genuinely enjoy mental challenges — a toy breed with real working-dog levels of trainability.
The Papillon (French for "butterfly," a nod to the breed's large, wing-shaped ears) descends from small companion spaniels favored by European nobility for centuries, formerly called the Continental Toy Spaniel. A drop-eared variety of the same breed is called the Phalène ("moth"). The AKC registered its first Papillon in 1915, and the breed celebrated 100 years in the AKC Stud Book in 2015.
Despite a delicate, elegant appearance, Papillons are known for surprising athleticism and intelligence — genuinely competitive in obedience and agility despite their small toy-breed size.
