Companion Dog Dental Chew Welfare and Safety

Dental chews and treats are widely used to maintain companion dog oral health, but significant variation in safety and efficacy among products means that some common options pose injury or obstruction risks that negate their welfare benefits.

Key Facts

Dental chews are a multi-billion dollar market in the US with highly variable evidence for efficacy
Hard dental chews including real bones, antlers, and hard nylon toys cause tooth fractures in a significant proportion of dogs
Tooth fractures expose the dental pulp, causing severe pain that often goes undetected until the tooth abscesses
The Veterinary Oral Health Council (VOHC) seal identifies products with clinical evidence for plaque and tartar reduction
Enzymatic dental chews and appropriately sized rawhide alternatives tend to have better safety profiles than extremely hard products
The tooth scratch test helps owners assess hardness: if you cannot scratch the product with a fingernail, it may be too hard

Welfare Considerations

Dental chew selection carries genuine welfare stakes because inappropriate products can cause the severe, often silent pain of tooth fractures. A slab fracture exposing the dental pulp is immediately painful and remains chronically painful as bacteria invade the exposed nerve tissue. Because dogs do not reliably signal dental pain, owners may continue using products that have already caused significant injury. Choosing VOHC-certified softer products or enzymatic chews with documented efficacy, while avoiding extremely hard products that fail the fingernail test, prevents dental trauma while still providing the oral health benefits that appropriate chewing products genuinely offer.

What You Can Do

Apply the fingernail test to all dental products — if you cannot make a mark, it may fracture teeth
Look for the Veterinary Oral Health Council seal when selecting dental chews or treats
Ask your veterinarian at every dental examination if any chewing products are causing visible tooth wear or fractures
Avoid real bones, antlers, hard nylon toys, and ice as chewing options despite their popularity
Combine safe dental chews with daily tooth brushing for the most effective plaque and tartar management
Report any tooth fractures or signs of dental pain to your veterinarian promptly for pain management and treatment
