Then, 'my dog' and 'you' are the agents, right? They do the process:>



The dog-walker will be AGENT and the dog, the one experiencing the action. "Walking" is figurative here - or a least delexicalised.

<[1] I need my dog walking.
My dog is to be out and walking.
You are to walk my dog.
=> The dog-walker will be "walking" the dog.>
