|Moxie and Misto, as alike as chalk and cheese. A feature, not a problem.|
From Genetic variation analysis of the Bali street dog using microsatellites come this little note:
While some breeds do have a low HE, such as the Boxer with a HE of 0.320, breeds like the Jack Russell Terrier have a high HE of 0.713 and overall their HE is higher than that of the dingo.
The Parson Russell terrier is NOT the Jack Russell terrier -- it is a dog squeezed into a small, closed, and increasingly less diverse registry with non-work based standards of "conformation" that will, predictably, lead to greater morphological exaggeration and increased disease.
The Kennel Club has never made a working breed; they have only ruined them. This is not an accident. Kennel Club rules and values inevitably lead to health and work failure.
Failure is is the only thing the Kennel Club has ever reliably produced.
