Tularemia in Dogs: Causes, Symptoms & Prevention

Tularemia, often referred to as “rabbit fever,” is a bacterial infection caused by Francisella tularensis. This zoonotic disease primarily affects rabbits, hares, and rodents, but dogs can also become infected through contact with these wild animals or via ticks and other insect carriers. Dog owners, especially those with pets that hunt or roam in wildlife habitats common across the United States, should be aware of this illness.

Understanding Tularemia in Dogs

The bacteria that cause tularemia thrive in moist, humid environments and can survive in natural settings for long durations. In the U.S., cases tend to rise during warm spring and summer months when ticks and insects are more active. Dogs typically contract tularemia by eating or handling infected rabbits or rodents, or from bites from ticks and certain flies carrying the bacteria.

While the disease is uncommon in dogs and often mild in otherwise healthy animals, it can progress quickly and become life-threatening for pets with weakened immune systems. Tularemia is contagious to humans as well, so it's crucial for dog owners to take precautions if their pet is suspected or diagnosed with the infection.

How Dogs Become Infected

Exposure to tularemia in dogs usually occurs through:

• Hunting, biting, or ingesting infected rabbits or rodents
• Contact with tissues or remains of infected wildlife
• Bites from infected ticks, fleas, or flies
• Drinking contaminated water sources
• Breathing in aerosols or dust from infected animal environments

During the heightened insect activity in U.S. regions such as Arkansas, Missouri, Oklahoma, and Kansas—areas with higher reported tularemia cases—dogs face increased risk of infection. Pet owners in these areas should be particularly vigilant.

Recognizing Tularemia Symptoms in Dogs

Signs usually appear within a day to two weeks after exposure and may rapidly worsen. Common symptoms include:

• Sudden onset of high fever
• Weakness and lethargy
• Loss of appetite or refusal to eat
• Limping or weakness in limbs
• Swollen lymph nodes, especially near the head and neck
• Abdominal tenderness or swelling, possibly due to spleen or liver enlargement
• Yellowing of the eyes or gums (jaundice)
• Discharge from the eyes or nose

If your dog displays any of these symptoms, seek veterinary attention immediately for prompt diagnosis and care.

Diagnosis and Veterinary Care

A veterinarian will undertake blood tests and possibly specialized assays to confirm tularemia infection. Early treatment often starts based on clinical signs to avoid delays, as timely therapy is critical.

Management involves administering targeted antibiotics like streptomycin, along with supportive treatments such as fluid therapy to prevent dehydration. In more severe cases, hospitalization and close monitoring may be required. Sometimes, surgical drainage of abscesses is necessary. Completing the entire course of antibiotic treatment is essential to avoid relapse.

How to Prevent Tularemia in Your Dog

Though no vaccine exists, you can lower your dog’s risk of contracting tularemia by following these tips:

• Consistently use veterinarian-recommended flea and tick preventatives
• Check your dog for ticks after time outdoors and remove any promptly
• Discourage hunting or scavenging of wild animals like rabbits and rodents
• Avoid allowing your dog to drink from stagnant or untreated outdoor water sources
• Steer clear of swampy, wet, or marshy areas where the bacteria may thrive

Preventative efforts are especially important in regions with rising tularemia incidents, such as parts of the Midwest and South.

Responsible Pet Ownership and Final Thoughts

Tularemia remains a rare but potentially serious bacterial infection dogs can catch from wild animals or insect bites. Recognizing symptoms early and seeking prompt veterinary care can significantly improve outcomes.

Protecting pets through regular parasite prevention, supervising outdoor activities, and avoiding contact with wildlife demonstrates good dog care and helps safeguard both animal and human health.

If you’re exploring options to bring a dog into your family, make sure to find Labrador Retriever puppies or other breeds from reputable breeders or adoption groups who prioritize ethical breeding and health standards. Thoughtful selection and lifelong commitment help ensure your furry companion stays happy, healthy, and less vulnerable to diseases like tularemia.

Educate yourself on ticks and other parasites common in your area to better protect your dog year-round.

Stay alert, keep your pet protected, and enjoy many joyful years together.
