Disproportionate Dwarfism

Affected dogs may display mild to severe disproportionate dwarfism. Limb shortening with increased angular deformities (e.g., outward turning of the paws), gait abnormalities, a relatively broad face, and an upward-turned nose may be observed.

Limb deformities become evident at a few months of age. Facial and body deformities may not be recognizable until early adulthood.

A diagnosis is made based on clinical examination, X-rays, and genetic testing.

There is no recommended treatment for dwarfism. Secondary mobility or arthritic changes may need to be managed.

Talk to your vet about your dog’s disproportionate dwarfism result so you can discuss how to support their mobility and long-term joint health.

This condition is not typically painful, but ramps or stairs can make it easier for your dog to reach furniture or navigate changes in height safely.

As arthritis may develop over time, keep your dog at a healthy weight and provide gentle, low-impact exercise to support joint function.

Watch for signs of stiffness or reluctance to move, and provide soft bedding and comfortable resting areas to make daily movement easier.

This variant was first described in the Dogo Argentino.

Penetrance: This variant is inherited in an autosomal recessive manner, meaning that a dog requires two copies of the variant to show signs of dwarfism.
