Spotting risky head shape can improve breed health - study
Cavalier King Charles spaniels have become increasingly popular in recent years owing to their ‘exaggerated head’ with large forward-facing eyes.
Judges assess head shape of 13 Cavalier King Charles spaniels 

New research suggests that dog health could be improved if breed show judges were to use their ability to identify differences in the shape of a dog’s head.

In the study, breed show judges used a checklist devised by researchers to identify different head shapes in King Charles spaniels. The spaniels had previously been identified as risk factors for Chiari malformation and syringomyelia.

Cavalier King Charles spaniels have become increasingly popular in recent years owing to their ‘exaggerated head’ with large forward-facing eyes. This recent change in head shape is markedly different to the traditional breed standard and research shows that it increases the risk of developing Chiari malformation and syringomyelia.

The dog show judges were asked to decide if the head shape of 13 Cavalier King Charles spaniels was “moderate” (traditional) or “exaggerated” (modern). This assessment was then compared to measurements of the dogs’ heads and MRI scan results identifying the presence of syringomyelia.

The findings show that judges varied in their ability (20 per cent to 80 per cent) to match the head shape with syringomyelia status, suggesting that visual assessment was possible.

Study leader Clare Rusbridge from the University of Surrey's School of Veterinary Science said: “Breed show judges are the considered experts in assessing the shape of a dog’s head. In selecting the champions of the breed they have great influence in determining what shape of head other breeders and the pet buying public will desire.”
 
“If we are able to show what facial and head characteristics are risky for dogs’ health then we can inform breed show judges who in turn can improve the health of the breed. To this end, we plan to continue our work in conjunction with facial recognition and medical imaging experts at the Centre for Vision, Speech and Signal Processing at the University of Surrey.”

The study, Pilot study of head conformation changes over time in the Cavalier King Charles spaniel breed, is published in Vet Record.
