Disproportionate Dwarfism
This disease is characterized by the abnormal growth, development, and remodeling of bones and cartilage. Disproportionate dwarfism involves relative length alterations of the limbs and changes in body proportions which may be visible as short limbs when compared to body length and/or as an enlarged head.

Signs and symptoms
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.Uncover health risks with Embark

What to do if your dog is at risk
Actions
- 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.
