Anaplasmosis is transmitted via the bite of a tick. A tick transmits the pathogen to the dog after 24 hours from the beginning of the sucking act. 


The pathogens of anaplasmosis in dogs are Anaplasma phagocytophilum and Anaplasma platys. Anaplasmosis is a bacterium that affects the granulocytes (Anaplasma phagocytophilum) and the thrombocytes (Anaplasma platys). Incubation period: Five to 20 days. 


Anaplasma infects the dog’s white blood cells and rapidly spreads throughout the body in this manner. It can take an acute as well as a chronic course. The infection is manifested by inflammation of the joints, weakness, weight loss, water retention, lameness, fever, enlarged lymph nodes, increased bleeding tendency and swelling of the spleen and liver. 

The causative agent can be detected by a blood test. 


Treatment is with an antibiotic, such as doxycycline, for about three to four weeks. Overall, dogs have a very good chance of complete control of the parasite. Chronic infestation is possible if diagnosed too late.
