I too think you have gotten some great advice. Also, do you offer the younger dog chew toys, bully sticks or himalayan chews? Anything that offers him long term attention at one sitting (15-20 min). I have found that while bully sticks and himalayan chews are a great treat, they also require a lot of energy, and after mine have chewed for a while, they are ready for a nap. Of course, this would be in addition to play time or walks and shouldn't be done in place of those activities either.
