Yeah I don't use antlers even for my big dogs. But they do get real meat bones.
I tried a lamb thigh bone for Magic once, and I was in the kitchen when I heard that special crunch sound ... I levitated down to the doggy den


He had snapped the thigh bone in half - about 10 minutes into the chewing time..... He thought it most unfair that I was taking his bone away! I had to offer him some other goodies in exchange. I now stick with bison and beef bones.
I also give turkey necks to the doggies, good cartilage for them. My butcher cuts them up for me - big dog size and small dog size.
I like healthy mouth but my dogs not so much. I use petzlife oral gel in both the spray bottle and gel bottle.
From Tropic clean I have a nubby ball (that has now disappeared)

that you can spray on the Tropic Clean and give to your dog to chew. Problem is all the doggies want what Magic has - so three balls for three dogs, two get left by the wayside and Magic spends his time protecting *his* ball. If I put them in their crate they only chew for a moment or two then leave it. Balls in their lexicon are for chasing and retrieving - preferably from the water
