Ticks are not only disgusting little blood-sucking creatures, they are dangerous, too. Ticks are one of the primary couriers for transmitting certain diseases, collectively called “vector-borne [or, tick-borne] diseases,” of which canine anaplasmosis is one. Sometimes referred to as “dog fever” or “dog tick fever,” canine anaplasmosis can be found throughout the United States, primarily in the northeastern, mid-Atlantic, and north-central states, as well as in California.
To see if anaplasmosis is in your area, visit the interactive map at dogsandticks.com and click on your region.
One form of this disease is spread to your dog from the black-legged tick, also referred to as the deer tick, which also transmits Lyme disease. Another form can be passed to your best friend from the brown dog tick.

So, how do these nasty ticks infect your dog with anaplasmosis? Ticks acquire the bacteria that cause the disease from feeding on an infected host animal, such as a rodent or a deer. Then, they pass the bacteria to your four-legged friend by biting him and ingesting his blood.
If Fido has been infected with anaplasmosis, he most likely will exhibit some of the following signs:
- Joint pain and stiffness similar to the symptoms of arthritis
- High fever
- Loss of appetite
- Neurological signs resulting in seizures and neck pain (infrequent)
Although the two forms of anaplasmosis present with different signs, both may pose a serious threat to your dog's health and can be difficult to diagnose, based on signs alone.
Upon examination, your veterinarian may recommend the following tests:
- An antibody test to identify if your pet has been exposed to anaplasmosis
- Urine tests to rule out urinary tract infections and to evaluate the kidney’s ability to concentrate urine
- Chemistry tests to evaluate kidney, liver and pancreatic function as well as sugar levels
- A complete blood count (CBC) to rule out blood-related conditions
- Electrolyte tests to ensure your dog isn’t dehydrated or suffering from an electrolyte imbalance
- PCR testing, in some cases
If your dog has been infected with anaplasmosis, your veterinarian will most likely prescribe an antibiotic, such as doxycycline or tetracycline. The good news is that, in most cases, symptoms begin to resolve within 1–4 days! Your veterinarian may recommend repeating the CBC after your pet has been on medication for a period of time, to make sure the antibiotic treatment has been effective. In more severe cases, some dogs require other medications or hospitalization.
Protecting your best friend from ticks is the most important step in preventing her from contracting any vector-borne disease! Because the signs of tick-borne diseases, like anaplasmosis, are so varied, it is vital that you have your pet screened routinely for any vector-borne illness. Screening tests are very fast and helpful because if your dog is infected, you can start administering medication as soon as possible.
The good news is there are several ways to protect your pet and very effective tick-prevention products and medications available both over the counter and from your veterinarian. To learn more about these products, as well as more about how you can prevent your pet from being bitten by a tick, we recommend (again) you visit dogsandticks.com.

Anaplasma is spread by ticks. As the weather gets warmer and dogs spend more time outside, they’re more likely to be exposed to these creepy parasites and all of the diseases they carry. Read more> Or learn more about dogs and parasites >
