Anaplasmosis in Dogs, Causes, Symptoms & Treatment

Anaplasmosis is a serious disease that is spread by the black-legged deer tick which can be found all across the US. Today, our Sacramento vets discuss what anaplasmosis in dogs is and how it is transmitted along with information about the treatment and prevention of this disease.

What is the cause of anaplasmosis in dogs?

Anaplasmosis is most commonly caused by a bacteria called Anaplasma phagocytophilum which is transmitted through the bite of an infected black-legged tick deer tick (which is also responsible for the spread of Lyme disease), or brown dog tick. This potentially serious condition can be found across the US but higher rates of the disease are reported in the Midwest, West Coast and Northeast.

What symptoms of anaplasmosis in dogs should I watch for?

Although some dogs with anaplasmosis show no symptoms at all, the most common signs are similar to severe flu symptoms. If your dog has anaplasmosis you may notice one or more of the following symptoms:

  • Lethargy
  • Pain
  • Fever
  • Loss of appetite
  • Bloody nose
  • Lameness
  • Joint pain
  • diarrhea
  • Vomiting
  • Cough
  • Breathing difficulties
  • Seizures
  • Meningitis
  • Ataxia
  • Chills

Will anaplasmosis in dogs go away on its own?

It is important to take your dog to the vet for an examination if they are showing any of the symptoms listed above. Left untreated Anaplasmosis can result in serious health complications for your dog including respiratory failure, organ failure, and bleeding problems. In very severe cases Anaplasmosis in dogs can be fatal.

How will my vet diagnose anaplasmosis in my dog?

Diagnosing Anaplasmosis can be tricky since the symptoms of this condition are somewhat vague and could be associated with a range of other diseases. Knowing where your dog has been and whether your dog may have come in contact with infected ticks can help your veterinarian with diagnosis.

Provide your veterinarian with as much information as possible regarding where your dog may have been in contact with the ticks, the symptoms your dog is displaying, and when the symptoms first began. The first symptoms of Anaplasmosis will typically appear in dogs between 2 - 4 weeks after being bitten by an infected tick.

If your veterinarian believes that your dog could be infected with Anaplasmosis they will perform a full physical exam to look for signs of the disease, and any ticks that may be living on your pet. Your veterinarian may also run an antibody test to determine if your dog tests positive for the Anaplasma phagocytophilum bacteria. 

What treatment options are available for anaplasmosis in dogs?

Anaplasmosis in dogs can be treated with a course of an antibiotic such as Doxycycline, Minocycline, Tetracycline, or Chloramphenicol. Most dogs show an improvement within 24- 48 hours after beginning the antibiotic treatment.

What are some ways that I can prevent my dog from contracting anaplasmosis?

One of the most reliable ways to help prevent Anaplasmosis in dogs is by keeping your pet on tick prevention meds year round. You can also help your dog to avoid contracting tick-borne diseases by keeping your pup away from areas where ticks are most likely to be hiding (long grass and brush), and checking your dog daily for ticks so that they can be removed before transmission occurs.
