Hi Carole, as a natural product I expect they would eventually. I usually throw them away if they start to crack or splinter, or if edges get a bit sharp, but I can’t say I’ve had one long enough to start smelling (not that my dog would mind).

Hi TJ, generally the “science” in this respect is very hazy, and most of these beliefs come from pet food companies. Usually these claims are worded “may help clean teeth” or “can fight plaque and tartar” which doesn’t necessarily mean they do, or not to any meaningful effect.

From personal experience I’ve seen the teeth of numerous dogs and cats have an incredible turnaround when raw meaty bones or tough meat/animal based chews are introduced. I can’t say I’ve seen the same for dogs fed wet mush, kibble, or Greenies. I wouldn’t consider the ingredients of brands like Greenies overly species appropriate either, but there aren’t really any regulations for any dog treats to be healthy anyway.

If I observe my own dog “chewing on” a bone or chew, there is definitely dental descaling going on! She also has a tendency to use one side of her mouth, and the teeth on that side are always completely clear of any plaque and tartar.

My 13 year old cat has always “chewed on” (I’m going to steal that chewed on/chewed through term!) raw meaty bones such as chicken necks/wings and the occasional dried meat chew, and he has no plaque or tartar whatsoever – not bad for an “elderly” cat.

Do you have any comments on this? To me horns and antlers seem like things a dog would be ‘chewing on’. Are there still dental benefits from this?

P.S. thanks for all that you do! I find the reviews really helpful
