Why does my senior dog's tick fever keep coming back after treatment?

Updated On September 23rd, 2025

Have a 13 year old street bitch. She was diagnosed on 1st Oct with tick fever (B. Gibsoni) with low platelet count of 40. Basis Pet doc consultation gave doxycycline hyclate twice daily for 21 days, multivitamins & liver tonic. She became fine but it relapsed again on 30th Nov. Doctor said it is due to stress from sudden onset of winter & advised to restart same medication. Query is (a) Is there no permanent solution & relapses due to stress (b) Does body not become immune to same medicine

Hello there! First of all a small correction- tick fever is caused by Erlichia and not by Babesia Gibsoni, although both conditions are tick born diseases and often cause almost similar symptoms and can even be found at the same time, they are not the same and treatment for each is different (B.Gibsoni is treated with Imidocrab). So it is important to make sure what was the diagnosis exactly. Tick fever can both reoccur if your dog gets infested with ticks again or can reappear spontaniously even if it has been treated for, this is especial true for chronic erlichiosis, your dog might need treatment from time to time (it has nothing to do with winter though). In chronic tick fever condition treatment might need to be given for more that 21 days and sometimes steroids needs to be prescribed as well.
