Retrieving a ball

Yesterday, Luna was playing with a big dog, Ruy, a yeloow lab. Ruy is very good at retrieving a ball. Luna has never done it before.

But while playing with Ruy, she has learned from her, just coping how Ruy does. Now she can retrieve a ball and bring it back to me. In fact, she runs faster than Ruy although her legs are too short. Luna takes all balls even if I throw a ball for Ruy; then she looks so proud of herself, wagging her tail. It was so funny.
