This inherited metabolic disorder prevents the dog's body from properly processing vitamin D or responding to its receptors. Without functioning vitamin D pathways, the skeletal system cannot absorb calcium, which is essential for building strong bones. This failure leads to severely weakened, soft, and poorly mineralized bone tissue.
Symptoms typically become noticeable in early puppyhood as the skeleton develops. Owners may observe stunted growth, bowed legs, a stiff or painful gait, and extreme sensitivity to being touched or handled.
The condition is incurable and requires lifelong daily management with specialized vitamin D supplements and calcium. Regular veterinary checkups and blood tests are necessary to monitor levels, with lifetime treatment costs ranging from 3,000 to 12,000 EUR.
Estimated range of typical treatment cost. Actual cost depends on severity, clinic and region.
