Skeletal Dysplasia 2, SD2

Affected dogs have abnormally short legs but a normal sized body.

Signs are first recognized by the time dogs reach 5 to 6 months of age.

Genetic testing and clinical signs can be used to diagnose this condition.

There is no treatment for this condition.

Talk to your vet about your dog’s SD2 result so you can discuss whether any signs are present and plan care if needed.

Most dogs with this result have mild limb shortening and do not experience pain or mobility issues.

Keep your dog’s environment easy to navigate with ramps or stairs if needed to help them reach furniture or vehicles safely.

This mutation was first described in Labrador Retrievers.

Penetrance: This mutation has an autosomal recessive inheritance, meaning that dogs must have two copies of the mutation in order to show clinical signs.
