Lyle loves to growl. His favorite thing to do is to pick up some kind of fabric toy, drop the other end in your lap and then growl at you when you try and pick it up. I assume this is "play growling".
He will also growl at significantly bigger dogs if they get in his space and ignore is cues.
That's been all the growling we've seen, other than that he's a sweet gentle lovebug of a dog.
Until recently, there have been a couple of time recently when my 10 year ol has either gone to take something away from him (e.g. Lyle was on DS's bed, where he sleeps chewing on a bone. But he was chewing very loudly right by DS's ear, so DS took the bone, and tossed it onto Lyle's bed, Lyle growled) or moved a part of his body (e.g. Lyle was lying next to DS, with his feet on top of DS's lap asleep in front of the TV, and DS wanted to move Lyle to go get something from the kitchen, when he picked up Lyle's foot to move it Lyle growled).
Is this something I should be worried about? A sign of possible aggression? A sign that he's not feeling well? He doesn't do these things to me, just to DS.

Your son needs to learn to not steal things out of a dog's mouth, at least not until this problem is resolved! He needs to learn the "trade game". If he takes something away from the dog, he needs to give him something in return. This will help the dog learn to accept things being taken away, because he knows he'll get something in return.
But it will definitely help. You've already stated that both of the incidents where he growled at your son involved him being up on furniture. Remove that from the equation and you will greatly reduce the chances of him repeating the behavior.

), it's not the being-on-the-furniture that's the issue.
