Understanding Osteomyelitis in Dogs
Osteomyelitis in dogs is a condition characterized by inflammation of the bone and/or bone marrow due to a bacterial or fungal infection. This infection can occur when the bacteria or fungi enter the bloodstream and spread to the surrounding structures, including the bone. It can also be introduced directly into the bone through traumatic injuries like fractures or deep, penetrating wounds. The most commonly affected areas are the limbs and the jaw (PetMD).
Definition and Causes
Osteomyelitis is the inflammation of the bone and/or bone marrow in dogs. It can occur suddenly (acute) or develop slowly over time (chronic). The infection can be caused by various factors:
- Systemic Infections: Infections that enter the bloodstream and spread to the bone and surrounding structures. These infections can originate from other parts of the body.
- Traumatic Injuries: Fractures or deep wounds that expose the bone to bacteria or fungi, leading to infection.
- Bites or Punctures: Deep wounds caused by bites or punctures that can introduce bacteria or fungi into the bone.
- Post-Surgical Issues: Following orthopedic surgery, metal implants can sometimes lead to infection and subsequent osteomyelitis.
- Dental Diseases: Oral tumors or other dental diseases can invade the jawbone and result in osteomyelitis (PetMD).
It’s important to note that osteomyelitis in dogs is not caused by viruses (PetMD).
Symptoms and Diagnosis
Recognizing the symptoms of osteomyelitis in dogs is crucial for early detection and treatment. Common signs include:
- Lameness or limping
- Swelling and pain around the affected area
- Reluctance to move or bear weight on the affected limb
- Discharge or draining wounds
- Fever and lethargy
If osteomyelitis is suspected, a veterinarian will conduct a thorough medical history and physical examination of the dog. Diagnostic tests such as X-rays, blood tests, and bone biopsies may be performed to confirm the diagnosis and identify the specific bacteria or fungi causing the infection.
