A little more about the acceptability and accuracy of dog breed identification by DNA analysis from: Rethinking dog breed identification in veterinary practice

To avoid problems associated with breed misidentification, we recommend that veterinary practices adopt a single non–breed-based term to describe all dogs of unknown parentage, rather than attempting to identify the predominant breed on the basis of visual inspection. For new clients and for new dogs acquired by existing clients, we recommend including a short statement on the new client or new patient sheet expressing the hospital’s position. A statement such as the following could be adopted: Because new scientific evidence has called into question the accuracy of visual breed identification of dogs, our hospital has adopted a policy to not identify canine patients by predominant breed unless the dog is purebred, the predominant breed of the dog’s parents is known, or the dog’s lineage has been established through the use of DNA analysis. [Emphasis mine]

It has been suggested that DNA analysis correctly identifies the breed of between 86% and 99% of purebred dogs. However, between 2007 and 2012, the stated mean accuracy of DNA analysis of first-generation crossbred dogs of known parentage increased from 84% to 90%, and breed identification accuracy of DNA analysis is expected to continue to improve.
