Understanding Osteomyelitis in Dogs
Osteomyelitis is a serious condition that can affect dogs, causing inflammation and infection in the bones. Understanding the definition, causes, symptoms, and diagnosis of osteomyelitis is crucial for effective management and treatment.
Definition and Causes
Osteomyelitis in dogs is the inflammation and infection of the bone. It can occur when bacteria or fungi enter the bloodstream and spread to the bone, or when the infection is introduced directly into the bone through a traumatic injury such as a fracture or deep wound (PetMD). Common areas affected by osteomyelitis in dogs include the limbs and the jaw (PetMD).
Causes of osteomyelitis in dogs can vary. It can be a result of systemic infection, traumatic injury, bites or punctures, post-surgical issues, or dental disease (PetMD). However, viruses have not been found to be a cause of osteomyelitis in dogs (PetMD).
Symptoms and Diagnosis
Recognizing the symptoms of osteomyelitis in dogs is essential for early detection and treatment. Common symptoms may include lameness, pain or discomfort, swelling of the affected area, visible infected wounds, fever, lack of energy, depression, weakness, and decreased appetite (PetMD). The specific symptoms may vary depending on the location of the infection, such as pain while eating and halitosis in cases of jaw bone infection.
To diagnose osteomyelitis in dogs, veterinarians typically begin by taking a detailed medical history and performing a thorough physical examination. Diagnostic tests are then recommended to confirm the presence of osteomyelitis. These tests may include a complete blood count (CBC), serum chemistry profile, urinalysis, X-rays, and fungal or bacterial cultures. In more severe cases, specialized imaging such as ultrasound or surgical bone biopsies may be necessary (PetMD).

Types of Osteomyelitis in Dogs
Osteomyelitis in dogs can manifest in different forms, depending on the duration and the nature of the infection. Understanding these types is crucial for accurate diagnosis and appropriate treatment. Osteomyelitis can be classified into acute versus chronic and bacterial versus fungal infections.
Acute vs. Chronic Osteomyelitis
Acute osteomyelitis refers to a sudden and severe onset of bone infection. It typically occurs after a traumatic injury, such as fractures, bites, or puncture wounds. The infection progresses rapidly, causing inflammation and destruction of the bone tissue. Dogs with acute osteomyelitis may exhibit symptoms like limping, pain, swelling, and fever.
On the other hand, chronic osteomyelitis develops over a longer period, often following inadequately treated acute osteomyelitis or due to underlying conditions like periodontal disease or systemic infections. Chronic osteomyelitis is characterized by persistent infection and the formation of bone abscesses. Symptoms may include intermittent lameness, draining wounds, and prolonged discomfort.
Bacterial vs. Fungal Infections
Osteomyelitis in dogs can be caused by both bacterial and fungal infections. Bacterial osteomyelitis is more common and can occur due to systemic infections spreading to the bone, traumatic injuries, post-surgical complications, or dental disease. The most frequently isolated bacteria in cases of osteomyelitis include Staphylococcus spp., Streptococcus spp., and Escherichia coli.
Fungal osteomyelitis, although less common, can occur in dogs, especially in regions with high fungal prevalence. Fungal infections, such as blastomycosis or aspergillosis, can invade the bones and cause osteomyelitis. These infections often arise from inhalation of fungal spores or from the spread of fungal infection from other sites.
Proper diagnosis of the type of osteomyelitis is essential for effective treatment. Your veterinarian will conduct a thorough evaluation of your dog’s medical history, perform a physical examination, and may recommend specific diagnostic tests and imaging techniques to identify the causative agent and determine the extent of the infection.

Diagnostic Tests and Imaging
To confirm the diagnosis of osteomyelitis and determine the extent of the condition, veterinarians may recommend a variety of diagnostic tests and imaging procedures. These tests help evaluate the affected bone, identify the presence of infectious agents, and assess the overall health of your dog.
Common diagnostic tests for osteomyelitis in dogs include:
-
Bacterial and Fungal Cultures: Cultures help identify the specific bacteria or fungi causing the infection, allowing for targeted treatment. The veterinarian will collect samples from the affected area and send them to a laboratory for analysis.
-
Complete Blood Count (CBC): A CBC measures various blood parameters, including white blood cell count, which can indicate the presence of infection or inflammation in the body.
-
Serum Chemistry Profile: A serum chemistry profile assesses the overall health of your dog’s organs and can provide insight into any underlying conditions that may contribute to osteomyelitis.
-
X-rays: X-rays are commonly utilized to assess the affected bone and surrounding tissues. They can reveal changes in bone density, bone destruction, or the presence of bone sequestra (dead bone fragments).
-
Ultrasound, MRI, or CT scans: In more severe cases or when additional information is needed, specialized imaging techniques like ultrasound, magnetic resonance imaging (MRI), or computed tomography (CT) scans may be recommended. These imaging modalities provide detailed visualization of the bone, helping to determine the extent of the infection.
By combining the information obtained from the medical history, physical examination, and diagnostic tests, veterinarians can confidently diagnose osteomyelitis in dogs. This comprehensive approach allows for appropriate treatment planning and management of the condition.
