Understanding canine brucellosis and taking appropriate preventive measures are critical for protecting the health and well-being of both dogs and humans.
Signs of Brucellosis in Dogs
Brucellosis in dogs can manifest in various signs and symptoms, affecting both males and females differently. Understanding and recognizing these signs is crucial for early detection and appropriate management of the infection.
Male Dogs
– Epididymitis: Male dogs infected with Brucella canis may develop epididymitis, an infection in the testicle. This can cause pain, swelling, and discomfort.
– Enlarged Scrotum: Infected dogs may also exhibit an enlarged scrotum, which may be tender to the touch.
– Enlarged Testicle: In some cases, one or both testicles may become enlarged.
– Skin Rash: Additionally, infected male dogs may develop a skin rash or lesions, which can be itchy or painful.
Female Dogs
– Infection of the Uterus: Female dogs infected with Brucella canis are prone to developing an infection of the uterus, known as pyometra. This can lead to abdominal pain, fever, and lethargy.
– Infertility: Infected females may have difficulty getting pregnant, as the infection can interfere with normal reproductive function.
– Vaginal Discharge: A persistent vaginal discharge, which may vary in color and consistency, can also be a sign of brucellosis in female dogs.
– Abortions and Stillborn Puppies: In severe cases, infected females may experience abortions or deliver stillborn puppies.
It is important to note that these signs are not exclusive to Brucella canis infection and can be attributed to other underlying health conditions. If you notice any of these symptoms in your dog, it is essential to consult a veterinarian for a thorough evaluation and proper diagnosis.
Transmission of Canine Brucellosis
B. canis bacteria can be transmitted through various means, primarily through contact with contaminated bodily fluids and mucous membranes. Understanding how this contagious infection spreads is crucial for preventing its transmission and reducing the risk of infection.
Genital Secretions, Urine, and Saliva
Infected dogs shed B. canis bacteria in their genital secretions, urine, and saliva. Direct contact with these fluids can lead to transmission. For example, a healthy dog licking contaminated urine or discharges from an infected dog can become infected themselves.
Sexual Transmission
Sexual transmission is another common route of B. canis infection. During mating, infected male dogs can transmit the bacteria to females. This makes it essential to test and quarantine breeding dogs to prevent the spread of the disease.
Inhalation and Mucous Membranes
Although less common, dogs can contract B. canis through inhalation of contaminated urine or contact with other mucous membranes. Inhalation of airborne bacteria or contact with infected fluids on surfaces can lead to transmission through the respiratory system or other mucous membranes.
To minimize the risk of transmission, it is important to practice proper hygiene when handling infected dogs or their bodily fluids. Using personal protective equipment and regular handwashing can greatly reduce the likelihood of contracting or spreading B. canis infection.
“Understanding how B. canis is transmitted is vital in preventing the spread of this bacterial infection. By taking precautions and maintaining good hygiene practices, we can protect both dogs and humans from the risks associated with canine brucellosis.” – Dr. Smith, Veterinarian

Diagnosing Canine Brucellosis
Accurate diagnosis of Brucella canis infection is essential for managing the disease and preventing its spread. Veterinarians employ a combination of tests to confirm the presence of B. canis and determine the stage of infection.
The most common diagnostic tool is the rapid slide agglutination test, which detects antibodies against B. canis in the dog’s blood. This test is reliable and can detect infections within 3-4 weeks after exposure. Positive results indicate active infection, while negative results require further testing to rule out a false negative.
In addition to the rapid slide agglutination test, other diagnostic tests may be used:
- The Tube Agglutination Test (TAT) measures the amount of B. canis antibodies in the dog’s serum. Finding elevated antibody levels suggests an active infection, although false positives can occur.
- The agar gel immunodiffusion test (AGID) is a serological test used to detect specific antibodies against B. canis. It provides a reliable confirmation of infection, but it may not be able to detect early-stage infections.
- ELISA assays (Enzyme-Linked Immunosorbent Assay) are laboratory tests that detect and quantify B. canis antibodies. These tests are highly sensitive and can help determine the stage of infection, assess treatment response, and monitor for relapse.
- PCR testing is a molecular method that detects the presence of B. canis DNA. It is highly specific and can be used to confirm infection even in the absence of antibodies, making it useful in early-stage infections or animals undergoing antibiotic treatment.
- Bacterial culture involves isolating and growing the bacteria from a blood sample, tissue, or other body fluids. While culture is considered the gold standard for diagnosis, it is time-consuming and requires specialized laboratory facilities.
Combining these tests enhances the accuracy of diagnosis and ensures a comprehensive assessment of the infection. Interpretation of test results by a veterinarian is crucial due to the complexity and variations in test performance.
Early and accurate diagnosis of canine brucellosis is vital for promptly implementing appropriate treatment measures, preventing transmission to other dogs, and mitigating potential zoonotic risks.
Treating Canine Brucellosis
When it comes to treating Brucella canis in dogs, it’s important to note that while antibiotics can help control the infection, there is currently no treatment available that completely eliminates the bacteria. Dogs infected with B. canis should be considered infected for life, making long-term management a crucial aspect of their care.
In some cases, surgical sterilization may be recommended as part of the treatment plan. This procedure can help reduce the shedding of the bacteria, decreasing the risk of transmission to other dogs. Additionally, supportive treatment may be necessary to manage and alleviate symptoms that may affect various organ systems.
