Canine Anaplasmosis

Canine Anaplasmosis [ an-uh-plaz-moh-sis ]

Sometimes referred to as dog fever, or dog tick fever, canine anaplasmosis is caused by the bacteria Anaplasma phagocytophilum or is transmitted by the deer tick (often referred to as the black-legged tick)-the same tick that transmits Lyme disease. Another form of Canine Anaplasmosis is caused by the Anaplasma platys bacterium carried by the brown dog tick. Although these two forms of Anaplasmosis present with different signs, both may pose a serious threat to your dog's health.

Most common signs of canine anaplasmosis:

  • Arthritis-like stiffness with painful joints
  • High fever accompanied by lethargy, loss of appetite, vomiting and diarrhea
  • Neurological signs (infrequent) resulting in seizures and neck pain
