Hypertrophic Osteodystrophy (HOD) in Dogs
Hypertrophic Osteodystrophy (HOD) is a high-severity orthopedic condition that can affect dogs of all ages and breeds. HOD is a painful developmental bone disease affecting rapidly growing large and giant breed puppies. It causes inflammation in the metaphyseal regions of long bones, leading to severe pain, fever, and lameness. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 2-8 months. Early signs to watch for include severe lameness, swollen painful leg joints, high fever, and lethargy. When treatment is required, costs are estimated at £500-£2,000 depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
