The prevalence of hip dysplasia in the New Zealand Huntaway


Canine hip dysplasia (CHD) is a debilitating disease in many breeds of domestic dog. Hip dysplasia can cause suffering and dysfunction. Given the requirement for farm dogs to work for long periods and over long distances, this condition could impact on the working life of an essential farm asset.

A study conducted in 1997 in the Taihape area found one in five Huntaways had hip dysplasia, and the majority of owners were largely unaware of the problem. This study aims to conduct a second survey to determine if the prevalence has changed over the past 20 years and also to determine the current prevalence of hip dysplasia in the NZ Huntaway nationally.

The study will use the PennHIP method to report the laxity profile of a group of Huntaways, in combination with the extended hip view. If we can determine the extent of the problem, we can give impetus into further research into the collection of genomic estimated breeding values (gEBVs) via SNP chips (single-nucleotide polymorphism arrays). Such information would allow the application of genomic selection and could reduce the incidence of hip and elbow dysplasia in the New Zealand Huntaway.
