Hmmm border collies usually want to work, herd stuff - sheep children, ducks, cars. Does he do ANYTHING besides sit and watch you try to play with his toys? Maybe he wants something different to do? Walks?

My bichons - well, the older 3 - have no interest in toys, and no interest in playing with other dogs. They love going for long walks with me. So that is what we do, for their exercise.

The youngest one will play with both toys and other dogs. But she is so full of energy, she even comes on the long walks, and is still ready to deal with a toy on our return.
