Paw Print Genetics is excited to announce that it has launched 12 new, very sought-after disease tests.  These tests compliment the breed-specific assays that PPG already offers, and cements our dedication to providing the largest menu of genetic tests for dogs. The following tests can be ordered as individual tests or may be part of one of our breed-specific panels that should be considered for any breeding dog.

Degenerative Myelopathy in the Bernese Mountain Dog

The Bernese Mountain Dog (BMD) has been identified as breed that can inherited degenerative myelopathy (DM). In this particular breed, two different mutations in the SOD1 gene have been identified. Degenerative myelopathy SOD1B is caused by a mutation of the SOD1 gene currently identified only in the Bernese mountain dog that is a different mutation from the common SOD1 mutation causing DM in a large number of breeds.  Bernese mountain dogs are known to develop a more slowly progressive form of degenerative myelopathy associated with the SOD1B mutation.  Both types of DM affect the white matter tissue of the spinal cord and is considered the canine equivalent to amyotrophic lateral sclerosis (Lou Gehrig’s disease) found in humans. Affected dogs usually present around 8-9 ...

The Shetland sheepdog is not just a collie in miniature form, but rather its own breed that has been crossed extensively with the long-haired, or rough, collie. Together they, and other similar breeds, are collectively referred to as collie, but make no mistake; the Sheltie is its own dog that has had many distinct (and extinct) breeds have contributed to its genetic makeup.

Placed in the herding group, Shelties in their modern form are more of a companion and show dog than working animal, however, they still retain many herding instincts and the intelligence associated with the group. It was developed from spitz-type dogs found on the islands of Shetland, which are northeast of England, and that were used for herding the smaller sheep and other livestock that developed there.

The rough collie obviously played a large role in the conformation and appearance of the Sheltie, but in addition to it and the Shetland spitz dog, the King Charles spaniel, Pomeranian, possibly the border collie and the extinct Greenland yakki all played a role in the smaller body and disposition of the breed.

The rough collie factors into the Shetland’s makeup with crosses taking place between the two breeds until ...
