We are giving Briar longer and longer periods of free time with the sheep - always under supervision. Today I was glad I had my camera. I'm still laughing. She is approximately 13 weeks old.
Briar with her sheep.
I was leaning on the fence, just supervising, when I noticed Briar alert on something. Three lambs were in hot pursuit of a chicken - YES! The lambs were chasing Gerald the Rooster!

Hulk, the testosterone-ridden baby, was in the lead and he wasn't letting up. Briar was fascinated.
Then she decided to join the game.
The lambs stopped as Briar chased the intruder.
Gerald doubled back.
As soon as Gerald was away from the sheep, Briar stopped the chase. Now I ask you, how can I teach the dog that chasing chickens is wrong when the SHEEP are chasing the chickens??? I'll give her credit though. She didn't continue the chase once the rooster got away from the sheep. Good puppy. But all that running did work up a thirst.
