Symptoms of osteitis in dogs:

1. In the early stage, X-ray examination only showed swelling of the soft tissue of the affected part of the dog. About 2 weeks later, the affected bone showed a nibbling-like destruction area and The edges of periosteal ossification are fuzzy and unclear.

2. Dogs with chronic osteitis have reduced bone density in the bone destruction area, and there may be "sequestral bones" in the bone cortex.

3. For dogs with sinus abscess, bone fragments may be released during flushing.

The causes of osteitis in dogs:

1. Exogenous infection, pathogenic bacteria infect bone tissue through wounds or surgical incisions. Seen in bite wounds, stab wounds, gunshot wounds and open fractures that directly damage bones.

2. Caused by the spread of purulent inflammation in the soft tissue around the bone.

3. Blood-borne infection mainly occurs in young dogs. It is an infection caused by pathogenic bacteria from other parts of the body transferring to bone tissue through blood circulation. Common primary infections include umbilical corditis, pneumonia, gastroenteritis, arthritis, etc.
