Hypertrophic Osteodystrophy(HOD)
Also known as: Metaphyseal Osteopathy · Skeletal Scurvy
Overview
What it is
Hypertrophic Osteodystrophy is an inflammatory bone disease that affects the growth plates in the long bones of fast-growing, large-breed dogs. It disrupts the normal blood flow to these growth plates, leading to painful swelling and abnormal bone development in the limbs. This skeletal condition is distinct from skull-affecting bone disorders and specifically targets the legs.
How it presents
Symptoms usually appear in puppies between 2 and 8 months of age, starting with sudden lameness, a reluctance to walk, and visibly swollen, warm leg joints. Owners may also observe a high fever, severe lethargy, and a loss of appetite.
Treatment
The condition is treatable with supportive care, such as pain relief, anti-inflammatory medications, and strict rest during growth phases. It is typically a temporary issue that resolves once growth is complete, with treatment costs ranging from €600 to €3,500 depending on the need for hospitalization.
