Animal companions and grappling

[Jasobandito]

So the grappling rules state that the grapple can continue "unless you move" does this mean that i cannot move under any means or that if i use a move action the grapple ends?

If someone shoves someone in a grapple does that end the grapple?

If you are riding a mount while you grapple someone can the mount still move and you maintain the grapple?

Since the Grapple rule is using the ambiguous "move" rather than a specific type of movement I would say that any form of movement, voluntary or not, would be considered "moving" where ending the grapple is concerned.

[Taja the Barbarian]

The rules don't allow you to carry or drag your target, so if you move at all (willingly or otherwise) you'll drop the grapple...
