Study reveals new insights into dog tooth fractures
The most common fracture among all samples in the study was a crown fracture.
Research follows increased concern over chew toys

A new study has investigated the external forces required to fracture a dog’s teeth while chewing.

Published in Frontiers In Veterinary Science, the study comes amid growing concern about the role of chewing on treats and toys in the fracture of large cheek teeth.

Researchers took 24 maximally pre-molar teeth, extracted from dog cadavers, and potted them in cylinders filled with acrylic. The cylinders were placed angles of 60 degrees before the team carried out an axial compression test.

They found that the highest force prior to a tooth fracturing was 1,281 N at an angle of 59.7 degrees. The most common fracture among all samples in the study was a crown fracture, followed by an uncomplicated crown fracture, complicated crown-root fracture and and uncomplicated crown-root fracture, respectively.

The researchers found no significant associations between dog breed, age, weight, impact angle, crown height or diameter, and the maximum force applied to the fracture. Crown height to diameter ratio was the only variable that remained significantly associated with maximum force, suggesting that a decreased ratio can improve resistance to tooth fracture.

‘The mean maximum force sustained by the tested teeth prior to fracture was within the maximum chewing capability of the average dog,’ the researchers conclude. ‘Dogs routinely exposed to hard treats and toys that do not yield significantly below this point might be at increased risk of fracture of maxillary fourth premolar teeth as a result of overexertion during chewing.’

The study was conducted by the University of Pennsylvania in collaboration with Mars Petcare and North Carolina State University College of Veterinary Medicine.

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

RCVS pays tribute to well-loved equine vet

The RCVS and the Riding Establishments Subcommittee has paid tribute to well-loved veterinary surgeon and riding establishment inspector, Rebecca Hamilton-Fletcher MRCVS.

Linda Belton MRCVS, RCVS President, said: "I, along with my colleagues on the RESC, RCVS Council, RCVS Standards Committee, as well as RCVS staff, was very saddened to hear of the sudden death of Rebecca, or Becca as we knew her, last week.

"She was a true advocate for equine welfare and in her many years on the RESC worked to continually improve the quality and consistency of riding establishment inspections, all in the interests of enhanced horse welfare and rider safety."
