Tularemia in dogs, also known as rabbit fever, is a serious bacterial infection caused by the bacterium Francisella tularensis. This highly contagious disease can affect a variety of animals, including humans, but dogs are particularly susceptible. Understanding the causes, symptoms, and treatment options for tularemia is crucial for all dog owners.
How Do Dogs Get Tularemia?
Dogs can contract tularemia through several ways, primarily through contact with infected animals, particularly rabbits.
- Tick Bites: The most common way dogs get tularemia is through the bite of an infected tick, particularly the dog tick (Dermacentor variabilis) and the wood tick (Dermacentor andersoni).
- Hunting and Ingestion: Dogs who hunt or scavenge can become infected by coming into contact with the carcasses of infected animals, especially rabbits and rodents. Ingesting infected meat or drinking contaminated water can also transmit the bacteria.
- Insect Bites: While less common, other biting insects like deer flies and mosquitoes can also transmit Francisella tularensis.
Recognizing the Signs: Symptoms of Tularemia in Dogs
Tularemia can manifest in various ways, making it challenging to diagnose. Symptoms can vary depending on the route of infection and the severity of the disease.
- Fever: A high fever is often the first sign of infection.
- Lethargy and Weakness: Infected dogs may become sluggish and reluctant to move.
- Loss of Appetite: Dogs with tularemia often refuse food and may show signs of weight loss.
- Swollen Lymph Nodes: The lymph nodes, particularly those in the head and neck region, can become enlarged and tender.
- Ulcers: Sores or ulcers may develop at the site of the tick bite or in the mouth if the infection was acquired through ingestion.
- Eye Discharge: Conjunctivitis and eye discharge are common symptoms, especially in cases where the infection originated from a tick bite near the eye.
Diagnosing Tularemia: What to Expect at the Vet
If you suspect your dog might have tularemia, it’s critical to seek immediate veterinary attention. Early diagnosis and treatment are crucial for a positive outcome.
- Blood Tests: Your vet will likely perform blood tests to check for signs of infection and to rule out other possible illnesses.
- Culture: In some cases, your vet may take samples of tissue or fluids from the affected areas to culture in a lab, confirming the presence of Francisella tularensis.
Treatment and Recovery: Giving Your Dog the Best Chance
Tularemia is treatable with antibiotics, but early intervention is key. The sooner treatment begins, the better the prognosis for your furry friend.
- Antibiotics: Your vet will prescribe a course of antibiotics, typically streptomycin, gentamicin, or doxycycline, to combat the bacterial infection.
- Supportive Care: Depending on the severity of the symptoms, supportive care such as intravenous fluids, pain relief, and nutritional support may be necessary.
With prompt treatment, most dogs recover fully from tularemia. However, delayed treatment can lead to severe complications, including liver and kidney failure, pneumonia, and even death.
Preventing Tularemia: Protecting Your Canine Companion
Prevention is always better than cure. Here are some effective measures to help protect your dog from tularemia:
- Tick Control: Use a veterinarian-recommended tick preventative year-round, especially during tick season.
- Vaccinations: While not widely available, there is a vaccine for tularemia that may be appropriate for dogs at high risk of exposure, such as hunting dogs. Talk to your vet to see if vaccination is right for your dog.
- Avoidance: Keep your dog away from areas heavily populated with ticks, such as tall grass and wooded areas, especially during peak tick season.
- Responsible Hunting Practices: If your dog hunts, use caution when handling wild game, especially rabbits. Wear gloves and thoroughly wash your hands after handling any animal carcasses.
Tularemia in Dogs: A Summary
Tularemia is a serious but treatable disease. By understanding the risks, recognizing the symptoms, and taking preventative measures, you can help keep your canine companion safe from this potentially deadly infection. Remember, early detection and veterinary care are crucial for a successful outcome.
FAQs about Tularemia in Dogs

The incubation period for tularemia is typically 3-5 days, but it can range from 1 to 14 days.
What should I do if I find a tick on my dog?
If you find a tick on your dog, carefully remove it using fine-tipped tweezers, grasping the tick as close to the skin as possible. After removing the tick, clean the bite area with antiseptic and monitor your dog for any signs of illness.
