Is there at least one working line in the breed of csw?

Rona - I personally call working dog every dog which at request from its owner does thing it would not do on its own accord and is able to do them for some period of time (half-hour to day to week, depend on type of work etc.)

So, if Tina just ran around and people could judge the situation based on her normal behavior, then she was not working. But if she responded to a command of sort, then she was working.

In my opinion wolfdog running along a bike at stable speed is working, while poodle fetching a ball for an hour might be just playing. Wolfdog running with it master without a leash stoppping for time and then running closer again is not working, while wolfdog running with its master at its master's speed is working. But this is again something for different discussion topic.
