Watched ingredients get highlighted on every product panel you open.
- Where it comes from
- Rubber plantations, then molded, mostly in the US for the major brands.
- Why it's in the product
- Chew toys that flex under the tooth instead of shattering or grinding down.
- Safety and toxicity
- The best-understood chew material available. It flexes rather than fracturing teeth, it is not a soft plastic so it does not need plasticizers, and it sheds far less than synthetics. No toy is indestructible, and pieces torn off any toy can obstruct.
- Interactions and who should be careful
- Natural rubber latex allergy exists in humans and is worth knowing if you handle the toy constantly. It is not a documented problem in dogs.
