The Japanese Spitz is classified by The Royal Kennel Club within the smaller ageing band, typically weighing 5–10 kg as an adult. Developed in Japan in the early 20th century, this striking all-white breed has a fluffy double coat and a cheerful, confident temperament, making it a popular companion breed worldwide.
What this means for your Japanese Spitz
Patellar luxation (a slipping kneecap) is occasionally seen in the breed, so any hopping or skipping gait is worth a vet check. Otherwise, the Japanese Spitz is generally considered a hardy, healthy breed with good longevity.
The bright white double coat sheds heavily during seasonal changes, and regular brushing helps manage loose fur and keeps skin healthy underneath.
When is a Japanese Spitz considered a senior?
Under The Royal Kennel Club's size-adjusted guidance, small breeds like the Japanese Spitz are generally considered senior from around 10 dog years old.
