Published in the Journal of the American Veterinary Medical Association, the research involved the analysis of the medical records of 27,000 dogs collected over 15 years at the University of California-Davis Veterinary Medical Teaching Hospital.

They looked for 24 genetic disorders such as cancer and diseases related to the eyes, heart, intestines and bones and found that the chance of inheriting specific diseases depended upon the condition itself and not by any breed.

Looking at it deeper, 13 of the 24 ailments saw no significant differences between when looking at the contrast between mixed breed and purebred dogs, which included conditions such as hip dysplasia, patellar luxation and mitral valve disease that are thought to be connected with purebreds.

However, ten of the diseases did show to be more common in purebred dogs, but this data should be very useful for vets and the canine community at large to look at prevention and treatment.

"This will ultimately impact all dogs, as there were no conditions found solely in purebred dogs. In addition, there was no single breed that was over-represented as a higher risk in the 10 (ten) disorders assessed," said Caroline Kisko, The Kennel Club’s secretary.

"Overall, the results indicated that genetic disorders were individual in their expression throughout the whole dog population, and that for some specific conditions there was a distinction between purebred and mixed breed dogs, and for other conditions, there was no difference to risk at all."

She hopes that the study should encourage potential dog owners to really think before making the decision between buying a purebred and mixed breed puppy, while remembering that it is vital to get all the right health checks done.
