Treats and chews
Are hard chews bad for dogs' teeth?
Last updated 23 September 2026 · How we write and check this
Short answer
Very hard chews, those that do not give at all under firm thumbnail pressure, carry a real risk of fracturing teeth, particularly the large upper premolar dogs use to crack hard objects. Softer chews with some flex are generally safer for daily use, while genuinely rigid items like antlers, weight bearing bones, and extremely hard nylon toys are best offered less often or avoided for dogs with a history of dental issues.
Why hardness translates directly into fracture risk
Tooth enamel, while strong, is not designed to withstand repeated, concentrated force from a completely rigid object, and a chew that transfers all bite force straight back into the tooth without absorbing any of it is the mechanical reason hard chews are linked so consistently to slab fractures in veterinary dental cases.
Which hard chews carry the most risk
Antlers and weight bearing bones sit at the top of the risk list because they offer essentially no flex, followed by very hard nylon toys, while items like bully sticks or dense rawhide alternatives, which soften slightly with saliva during chewing, sit noticeably lower on the same risk scale.
Making hard chews safer if you still want to offer them
Limiting hard chews to shorter, supervised sessions rather than all day access, and watching closely for the dog favoring one side of the mouth afterward, reduces but does not eliminate the risk, so dogs with any prior dental history are usually better served by softer alternatives altogether.
Key takeaways
- Chews with no flex at all transfer bite force directly into teeth, raising fracture risk.
- Antlers and weight bearing bones carry the highest risk, followed by very hard nylon toys.
- Softer chews like bully sticks soften with saliva and sit lower on the risk scale.
- Dogs with a history of dental issues are usually safer avoiding the hardest chew categories.
