Small Dog Breeds Whose Size Stays Consistent Over Time
1. Japanese Chin

Regal Companions with a Gentle Demeanor

Their long history as cherished indoor dogs has preserved their elegance and temperament over generations.

Loyal Companions and Watchdogs
These dogs thrive on human companionship and rarely enjoy being left alone. Pekingese are alert and will bark to protect their home, though their exercise needs are minimal—short romps or indoor play usually suffice. Their loyalty makes them excellent lapdogs and family pets.

Ancient Royal Origins
Dating back to around 700 A.D., Pekingese were cherished in Imperial China and often kept as “sleeve dogs” by palace nobility. Their lion-like appearance symbolized Buddhist ideals, and their royal status helped secure the breed’s continued popularity.
Grooming and Care
The Pekingese’s profuse coat is a hallmark, requiring daily attention for show dogs or regular upkeep for pets. Facial wrinkles and long hair around the ears, tail, and rear need careful cleaning. Their short muzzles make them prone to snoring and heat sensitivity, so temperature management is essential.
