Pekinese dog, Japanese spaniel
狆 centers on a specific small companion dog breed: the Pekinese or Japanese spaniel. The meanings are direct breed names rather than a broad concept.
狆 is a phono-semantic compound: the animal radical 犭 (dog) combines with 中, which likely provides the sound チュウ. The character was created specifically to name the Pekinese or Japanese spaniel breed.
The left side 犭 is a dog, and the right side 中 suggests something small and central. Picture a tiny Pekinese dog sitting proudly in the middle of a room.
For チュウ, imagine a tiny Pekinese dog chewing on a toy: chew -> チュウ, and the dog is the center of attention.
