Or if one of the dogs is too old to play. 
My younger dog started chasing the sheep each evening and I was just getting my shoes on to nip it in the bud~then my last look out the window was an eye opener....the sheep were chasing the dog right back. Every evening they got into a pattern where they just seemed to need to burn off steam before bedtime. It was comical to watch them play together....there was never any contact except for nose touches but there sure was a lot of chasing. Round and round the garden, first one way and then the other. When done they would walk away like they never knew each other.
All the while my old GP mix, Lucy, would look on with a distinct measure of disdain on her face as if to show how disgraceful it was for a dog to play with sheep! She never joined those reindeer games...
