Dog Panosteitis, also known as Eosinophilic osteitis, is a bone disease characterized by bony proliferation and remodeling causing pain and lameness. It belongs to motor system disease, which symptoms mainly is impaired movement.

Dog Panosteitis is a spontaneous and self-limiting disease. Mostly occur in young dogs of larger dog breeds. There are slightly more males than females in the affected dogs. The average age of onset is 5 to 12 months of age. The places of the disease is at the backbone and metaphysis of the tubular bone. The cause of this disease is still unclear. Because German shepherds are susceptible to this disease, genetic factors are considered to be a cause of this disease. The disease was first reported in Europe in 1951, calling it chronic osteomyelitis, and later also known as eosinophilic osteoostitis, youth osteomyelitis, endogenous osteowarts, and internal bone disease. This disease is only seen in dogs.

The Causation of Dog Panosteitis

The specific etiology of Dog Panosteitis is unknown, with the formation of endosteal and new bone formation. The new bone formation is obvious. The main lesion is the trabecular bone embedded in the bone marrow to form endosteal bone. The bone marrow contains a large number of cells and has different degrees of fibrosis , But no chronic inflammation, acute infection, or malignancy occurred.

Mainly Symptoms of Dog Panosteitis

The dog suddenly limped but had no signs or history of injury. The limping naturally eased after a few days, but appeared on the other limb in a few weeks. In chronic cases, the recurrence interval can be as long as several months. The onset tubular bones include ulna, radius, arm bone, femur, and tibia. As the age increases, the severity of symptoms becomes lighter, and the interval between relapses increases.

Diagnosis of Dog Panosteitis

According to the clinical symptoms, the sick dog has normal body temperature and no muscle atrophy. Pain occurs in symptomatic symptoms. In severe cases, anorexia and burnout may occur. During the X-ray examination, because the disease is progressive, it may be normal to start taking X-rays, which is due to the appearance of clinical symptoms. If you want to confirm the diagnosis, it is best to take another 15 days later. X-rays will show bones Trabecular shape is fuzzy, density increases, bone marrow cavity is plastic, cortical bone thickens, and then there are spots in bone marrow cavity, thickening of cortical bone. It generally does not expand to the epiphysis. Approximately 30 days later, the medullary cavity where the lesion first appeared began to recover, and 70 to 90 days later it can completely return to normal. However, long bones that have been affected by this disease many times will also deform and thicken. Bone marrow loses normal hematopoietic activity.

Treatment of Dog Panosteitis

There is no effective treatment for the cause. Commonly used is symptomatic treatment, pain relief, anti-inflammatory, such as salicylic acid medication, butazodine, etc., can also try cortisone medications.
