Here's why it's tricky to answer:
* Variety of breeds: The imperial court likely kept a wide variety of dogs, some with heavy shedding coats and others with lighter shedding coats. There wasn't one specific breed that was exclusively favored.
* No historical records: We don't have specific records on the types of dogs kept by the imperial court and their shedding habits.
* "Chinese imperial dog" is not a recognized breed: This means there's no official standard for the breed, making it impossible to know for sure about their shedding tendencies.
To answer your question more broadly, most dog breeds shed to some extent. Some shed more than others, but all dogs lose some fur naturally as part of their hair growth cycle.
If you're interested in specific dog breeds with low shedding, you can research those online or consult with a veterinarian or breeder.
