Query: Still holding up

Almost 3 year old lab mix, not a heavy chewer but can do damage if he wants to. So far, squeakers and body are holding up just fine, no rips, tears or wear on appendages. However, the eyes are now mysteriously gone. Not a huge deal, they seemed to have just fell off at some point in the past week or so, both of them. I'm sure due to slobber and not abuse as he only grabs the toy when he wants to go outside, not really a chew toy more just grab it and let us know it's time to go outside.
