My 2yr old female Havanese was positive for anaplasma phagocytophilum platy on a routine test before adoption. Given doxycycline 100mg daily for 30 days. She has no symptoms abnormal. She plays and eats well. Do I need to be concerned about future health problems? Any routine test that need ordering every year?

Hi there and thank you for using pet coach to address your concern. Generally I will treat for 4-6 weeks with Doxycycline and then send out an anaplasmosis PCR to see if the patient is still positive. The test used in most vet clinics is a simple snap test that detects circulating antibodies to the anaplasma. It is likely that Molly will be positive on this snap test for years to come. This does not mean she is actively infected, just that she has had previous exposure to the infection. If you want to confirm she is negative after treatment, then a PCR test would be the test to run. Generally after successful treatment, I do not see any health complications. No annual testing is needed but a PCR might be something to consider running for the first 12 months every 6 months after treatment. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns. I am also available via consultation if needed.
