This is a Skeletal condition.


What is Osteochondrodysplasia?

As a fetus, most of the bones of the body actually start as cartilage models of themselves. Over time, the cartilage is replaced with the bones that you (and your dog) are born with. Dogs affected with osteochondrodysplasia have a mutation in the SLC13A1 gene, which codes for a protein that transports minerals into the developing bone. Defects in this gene disrupt the cartilage to bone transition, leading to inappropriate skeletal development.

What are the signs & symptoms that develop in affected dogs?

Affected dogs have abnormally short legs but a normal sized body. They can also have changes to their rib cage and an underbite.

When do signs and symptoms develop?

Signs are first recognized in puppies.

What actions should I take if my dog is affected?

  • This is not typically thought of as a painful condition, but you may need to place ramps or stairs to assist these dogs if you want them to sleep on the bed or couch.
  • Affected dogs may not walk or stand in a normal position.
  • Severely affected puppies may require nursing care. Others may have breathing difficulties due to flattened rib cages.
  • Arthritis typically develops because of the skeletal changes.
