Panosteitis in Dogs

Panosteitis refers to a short-lived (self-limiting) and painful condition characterized by limping and lameness. It is a condition that affects the long bones in the legs of young dogs, usually between the ages of 5 to 18 months. It can occur with any breed, but it is more common in medium- to large-sized dog breeds.

The inflammation can affect one or more of the dog's limbs, making it challenging and painful to move around. With treatment, the inflammation can be reduced and the animal can regain full function and activity.

Panosteitis can affect both dogs and cats. If you would like to learn more about how this condition affects cats, please visit this page in the PetMD health library.

Symptoms and Types

Lameness is often characterized by trouble walking on the front legs, as there is often a deep pain associated with the bones. While the inflammation is more common in the front legs, it is also found in the back legs.

Some dogs also exhibit fever, depression, weight loss, and anorexia. Additionally, if the condition is not corrected, some dogs may experience loss of muscle mass (atrophy) over time with the lack of muscle usage.

Causes

Overall, the causes of panosteitis are unknown. While lameness can affect any breed at any age, it is most common in younger breeds, and in particular, the German Shepherd. The lameness may occur on its own or it may be accompanied with other orthopedic diseases.

Diagnosis

Joint pain can last from days to months, and will range from mild to severe. Your veterinarian will examine your dog to rule out underlying conditions other than inflammation of the bones. X-ray imaging and blood analysis will be used to search for any underlying conditions. In most cases, the inflammation will be the cause of the pain and can be reduced with drug treatment.
