Day Thirty Seven: It’s another hot day and Happy is quite. I get the play out by running him around the round pen. He is lazy today and I think I’m working as hard as he is keeping him going so I decide to get on. He is good today, walk , trot and loped both directions nicely. I put a slow sheep in the pen and ask Happy to track it. He is a natural and hooks on with only a few minutes. He is still green so I try to keep it slow but Happy wants to eat this little thing and I have to pull him up. He get nervous, like before with me pulling on his mouth but the sheep keeps his attention and he is happy to follow the sheep again. I follow the sheep about 15 minute and Happy is stopping with the sheep and waiting.
