Lyme disease isn't the only tick-borne illness that can sicken your pet. Erlichiosis may also make your furry friend miserable. Fortunately, antibiotic treatment can kill the bacteria responsible for the illness.
What is Ehrlichiosis?
Your dog may develop canine monocytic ehrlichiosis if it's bitten by a brown tick carrying the ehrlichia canis bacteria. The ticks are found in every state in the continental US, but seem to be particularly active in the warmer parts of the country. Ehrlichiosis in cats is rare, although the illness does occur occasionally.
Another form of ehrlichiosis, known as canine granulocytic ehrlichiosis, occurs when your pet is bitten by a lone star tick. This tick thrives in the Midwestern, Southeastern and Eastern parts of the country.
What are the Symptoms of Ehrlichiosis?
Common symptoms of ehrlichiosis in dogs include:
In addition to fever, enlarged lymph nodes and eye inflammation, cats may develop swollen joints, anemia and trouble breathing.
Symptoms usually appear one to three weeks after your pet is infected. If your dog or cat doesn't receive treatment at this time, the disease may progress to the subacute or chronic phases. Chronic ehrlichiosis can affect your pet's ability to produce adequate numbers of red and white blood cells and may even lead to death. Pets that are already sick with another illness or have compromised immune systems may be more likely to develop severe or chronic ehrlichiosis.
How Is Ehrlichiosis Diagnosed and Treated?
It's not always easy to diagnose ehrlichiosis, as many other illnesses share common symptoms, including Lyme disease, Rocky Mountain spotted fever and lymphosarcoma. Blood, fecal, and other lab tests can help your pet's veterinarian narrow the possibilities.
Some pets may test positive for exposure to the bacteria that causes the disease, yet never become sick. If your pet's routine bloodwork includes a positive result for the ehrlichiosis bacteria but he or she has never been sick, treatment probably won't be necessary. Treatment is usually recommended only if your dog or cat has a positive test result and displays symptoms of the disease.
Antibiotics, such as doxycycline, tetracycline, or minocycline, may be prescribed if your furry friend is diagnosed with ehrlichiosis. Most pets will begin to feel better one to three weeks after beginning antibiotic treatment. It's important to give your pet all the medication, even if you happen to notice an improvement in the symptoms after a few days. In the later phases of the disease, dogs may need blood transfusions or steroid treatment.
