Hachi is feeling so much more at ease since he's been able to run around again. Those 14 days of rest felt like 14 years!
He has naturally bonded strongly with R so I tend to take him outside to play with Shyla. If R were with us, I'm not sure that Hachi would look to Shyla to play.
Shyla's favorite game is "stick". She won't accept any substitute for real sticks - no toys, no fake sticks. It's got to be a real stick. Shyla tries very hard to slow herself down enough that Hachi can play with her. She often "offers" Hachi the stick, as you can see.
So, I had to laugh when he brought me a "Hachi-sized stick" all by himself!
