About Anaplasmosis in Dogs

Ticks can cause a variety of potentially serious diseases in dogs, such as anaplasmosis, which can cause a number of serious symptoms. Today, our Tumwater vets discuss the symptoms and long-term effects of anaplasmosis in dogs and how it can be treated and prevented.

What is anaplasmosis in dogs?

One of the most common tick-borne diseases in dogs is anaplasmosis. This is caused by a bacteria called Anaplasma phagocytophilum. It is spread through being bit by an infected black-legged tick, deer tick (also responsible for the spread of Lyme disease), or brown dog tick. This potentially serious condition can be found across the US, but higher disease rates are reported in the Midwest, West Coast, and Northeast.

What are the symptoms of anaplasmosis in dogs?

While we occasionally see cases of asymptomatic anaplasmosis in dogs, others may have flu-like symptoms. If your dog has anaplasmosis, you may notice one or more of the following:

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

What are the long-term effects of anaplasmosis in dogs?

If your dog begins to show symptoms of anaplasmosis, you should bring them to a vet as soon as possible. Undiagnosed and untreated anaplasmosis in dogs 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.

Sometimes, a dog can be treated successfully and may continue to test positive for the infection. This does not indicate an active infection, so a second round of antibiotics is unnecessary and usually not recommended.

How will your vet diagnose anaplasmosis?

Diagnosing anaplasmosis can be tricky since its symptoms are somewhat vague and could be associated with various other diseases. Knowing where your dog has been and whether it 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 began. The first symptoms of anaplasmosis typically appear in dogs between two to four weeks after being bitten by an infected tick.

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

How is anaplasmosis treated in dogs?

Anaplasmosis in dogs can be treated with antibiotics such as Doxycycline, Minocycline, Tetracycline, or Chloramphenicol. Most dogs improve within 24 to 48 hours after beginning the antibiotic treatment.

Does anaplasmosis go away on its own in dogs?

Anaplasmosis is a disease that always requires treatment. It can not go away on its own, and if left untreated, anaplasmosis in dogs can have serious long-term effects and may be fatal.

How to Prevent Anaplasmosis in Dogs

Preventive tick medication given throughout the year can go a long way in preventing your pup from being affected by tick-borne diseases. You can also help your dog 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.
